Penis Size & PE Growth Rate Study @ Thundersplace

METHODOLOGY

Data pertaining to penis sizes and penis enlargement was obtained and analyzed from the publicly available database of user-reported penis enlargement log entries at https://www.thundersplace.org on October 14, 2014. The anonymous nature of https://www.thundersplace.org provides little incentive for website users to intentionally falsify entries on a large scale, however an algorithm was adopted to increase the quality of the raw data prior to analysis. Website users were excluded from the study if the data they entered met any of the following criteria.

Excluded Users:
a) starting erect length (bone-pressed) of greater than 11 inches
b) starting erect length (bone-pressed) of less than 1.5 inches
c) ending erect length (bone-pressed) of greater than 13 inches
d) ending erect length (bone-pressed) of less than 2 inches
e) starting midsection erect girth of greater than 8.5 inches
f) starting midsection erect girth of less than 1.5 inches
g) ending midsection erect girth of greater than 8.5 inches
h) ending midsection erect girth of less than 1.5 inches
i) OVERALL LENGTH LOSS REPORTED
j) OVERALL GIRTH LOSS REPORTED
k) LENGTH GAIN OF GREATER THAN 5.5 INCHES
l) GIRTH GAIN OF GREATER THAN 3.5 INCHES
m) LESS THAN 3 THUNDERSPLACE LOG ENTRIES (FOR ALL STUDIES UNLESS OTHERWISE NOTED)

Exclusion (m) should be quite effective in improving data quality, based on the premise a user goofing around with the log entry system or entering an intial false entry is not likely to enter 3 or more entries. Exclusion (m) could not be applied in every study and is noted where it was not applied.

* All length measurements are bone-pressed. All girth measurements are at midsection.
** Thundersplace.org user database of log entries dated Oct. 14, 2014 used in this study is attached to this thread.

Penis Size, Pre-PE, By Percentile

User reported pre-PE penis sizes correlate well with other penis size studies. As penis size varies based on race, ethnicity, erection quality and possibly other factors only studies within these groups will correlate extremely closely. Thundersplace.org data encompasses a wide variety of penises from all over the globe. Erection quality would be expected to be higher than studies done by Doctors or Nurses. Also, Thundersplace users would be more likely to have knowledge of PE already and possibly already have some PE related growth, though this is likely nominal given the close correlation with other studies. These factors likely account for the minor differences in reported penis size from other studies.

Penis Size, Post-PE, By Percentile

Interestingly, while it is demonstrated that smaller starting sizes have more initial growth potential on average, comparing the bottom and top ten percentiles of the pre-PE and post-PE penis sizes appears to indicate greater growth potential in larger penises, which does line up with theories about the mechanisms of penis enlargement.

Post-Initial Penis Size Increase Compared to Pre-PE Penis Size, Percentiles

It has been demonstrated that smaller starting penis size is correlated with a higher initial growth rate when starting PE. This study examines the potential relationship between pre-PE penis size and growth rate after so-called newbie gains are exhausted. Results do not appear to reliably indicate any advantage to the smaller penis size category with longer term PE. Overall pre and post PE sizes in a study above appear to indicate greater growth potential with larger pre-PE penis size.

PE Attrition Rate

61.9% of users submitting a single log entry on Thundersplace submitted only 1, indicating that even users initially motivated enough to register and add a log entry, never add another, likely a result of discontinuing or inconsistent PE activities.

PE Motivation Compared to Pre-Penis Size

Average number of log entries were calculated within various penis size ranges encompassing both length and girth for users who submitted 2 or more log entries, to examine a possible connection between PE motivation and pre-PE penis size where motivation is measured by number of log entries. Average log entries were 4 for all penis size groups except the largest. The largest penis size groups, penises with a Pre-PE length of 8.5-9.5 and/or Pre-PE girth of 6.0-7.0 averaged 3 log entries. This appears to indicate little difference in motivation based on penis size, with a slight drop on the larger end of the spectrum.

PE Elapsed Time in Days to Realize Penis Size Increase of X, Percentiles

Number of PE Days refers to the number of days elapsed between the first log entry and the subsequent log entry when x size increase was reported.

Thundersplace Modified PE Database

I am attaching a spreadsheet to this post containing modified versions of the Thundersplace PE database that may be easier for some users to use, for instance if you know how to sort by a particular column using Excel you can sort by length gain, girth gain, etc. The first spreadsheet tab is the original database I downloaded from Thundersplace containing data through Oct 14, 2014. The rest of the tabs are modified versions and filtered by excluding users based on exclusions (a)-(m) from the very top of this post to achieve higher quality data.

Very interesting - thanks!

Very interesting and impressive work there. Thank you.

I still find it interesting that our starting sizes are so much bigger than the reliable size studies out there. I often wonder why that is.

YW - DW, I find some of the information useful to formulate realistic expectations and hopefully it will help others in the same way.

Thick - My opinion is the biggest factors for the difference are race/ethnicity, and to a lesser degree predisposition to already have some gains from PE prior to first log entry and higher EQ than in non-self-measured studies. IMO and experience, race is the single greatest factor when it comes to differences in reported length, which is why I think there is always going to be a lot of variability from study to study unless this is controlled for. The first study here actually aligns very closely with pre-PE sizes reported here, in fact Thunders is smaller than in this study as progressing up the percentile rank. The third study on that page uses Chinese data so it’s useless and any averages derived using it are useless unless we are only trying to figure out Chinese percentiles and averages. If another study was performed in China, I would bet both datasets would be extremely close.

Actually all studies show little or no variation of penis length among different ethnicitis. The average is 5.8” BP.

Interesting, only thing is the numbers seem a little odd to me. For instance, I’m 7.1x5.2 now BPEL, and if I go by pre-PE stats that is 84th percentile by 70th percentile, which seems to match a lot of studies. Now if I go by post-PE stats, then I am only 42nd by 37th. This would mean well over 50% of the people who PE’ed on Thunders are over 7 long and 5 around? Somehow that doesn’t seem right to me as I doubt half the people here are at or over 7.25x5.3 BPEL.

Also, to maintain the same percentile figures, I’d need to go to at least 8x5.7 BPEL, which I do hope is at least possible, but still the post-PE stats seem a little high, percentile wise.

Fair enough Marinera, the ethnicities part or inter-race variation is just a guess (I assume when you say ethnicity you are not talking about race), and it would be more applicable to regions of greater genetic variation, like Africa, than others with less genetic variation like European or Chinese.

Phoenix - Remember what you are up against in those ending stats - this site has existed over a decade I believe and the average PE duration sampled was 804 days if I remember right (last log entry date - first log entry date) days for people that added 3 or more log entries, you have only been here a short time. You are not up against just the guys that frequent the board right now, whom also will tend to be newer like yourself, but the entire historical population of Thunders.

Thing is, most people don’t even know PE works much less do it, so if you are interested in comparing yourself in a percentile that represents the general population it would still be a comparison to starting percentiles.

I am meaning ethnicities because there aren’t human races’ as far as I know. Humans are one race. Variations are ethnical traits. People from Nigeria seems to be as long on average as people from China.

Marinera, I respect your opinion - your posts and opinions are lucid and intelligent. I disagree with you on this point though based on evidences I have seen and experienced.

True, I didn’t think of it that way. I’ve lurked on other PE forums for a while before committing and joining, but I guess if 7” is supposed to be considered the borderline to ‘large’, that well over 50% of the people who PE’ed have surpassed that marker. I guess too it’s because I’ve always figured most, if they keep at it, might gain 1-2” in length and maybe 1” in girth, but for some reason those numbers seem like average gains are a lot higher.

Disagree how much you want but there are tons of studies here
Penis Size: The True Average

(a good number posted by me) and what they say is that there isn’t any significative variation in length among blacks, caucasians, asians or whatever.

As for your personal experience, why do you suppose that it has a greater statistical reliablity than the experience of anyone else?

TBH it’s not a discussion I care to get caught up in. I made the statement assuming it was basically a given, it’s a cultural thing I guess, here in America where we have a lot of diversity any woman you ask who’s been with a significant number of men from various races will describe significant variation, there are studies that suggest the same two of which I already posted, and as you pointed out there are studies that can be interpreted quite the opposite. I think by far the most important and interesting data is related to growth rather than starting size.

I love this, thanks! I may want to do this in a histogram plot form though. Do you already have that and could post it somewhere? I have a Google Drive account could host it out of if wanted…

Which ones?

Marinera - The third comment from the top contains the link to results from the 3 studies I was referring to, there was another that I read that found significant variation but I didn’t bookmark it or anything so I don’t know where I saw that one.

AVG - Serenity73 posted these graphs to another thread, I am attaching them here. It would be great to get graphs completed of all the studies, and maybe embed them in a post, yeah I am afraid the amount of information in the original post may be a little intimidating to some as it’s not a very friendly format.

Also it looks like the original post perhaps I forgot to attach the original database and modified databases so I am attaching them here. Ah I see, xlsx is not valid here, I will save as xls and attach.
