Average Gains and Starting Measurements

Wait, is the data collection manual? I thought there was a database somewhere that had the entries. No worries.

We used to have the option to download everyone’s data, not anymore.

In the future we may bring it back, if needed.

Got it. I think it would be a good feature. You may be able to report things such as shifts in the average over time I.e. Every 10 years. Thunder’s may become the only source offering that type of insight with a rich data set, anomalies and errors considered.

Why would the average starting size as stated above of approx. 6.4 inches be so much larger than the oft quoted studies of approx. 5.2 inches? Is something amiss?

I would think that more guys who felt that they were below average would be more motivated to practice PE than those are already well above the statistical mean.

Does anyone have thoughts regarding this? Are the studies lying to protect our egos?

The data set he is analyzing is self reported data from members here. It is not a statistically valid data set if the objective is to analyze the range of adult penises of the world population.

Your comment that “I would think that more guys who felt that they were below average would be more motivated to practice PE than those are already well above the statistical mean” has some huge assumptions incorporated in it.

It may be true that more below average guys would be motivated to practice PE. Since every member has not posted stats, we do not know the composition of the members who did not post them. The resultant average size of 6.4” strongly suggests that the below average members did not post their stats (many reasons why) and more of the average to above average members did.

Don’t forget that there many problems (statistically) with self reported data.

If you want to find the average height of adult males, you don’t use all NBA players as the data set. If you want to estimate the average height of NBA players for next season, you can use the average height of nba players from this season or previous seasons to do so.

CalcSD has western average of studies 14,4cm / 5,7”. Lifestyle Condoms study researcher measured 14,93 cm / 5,88”.

As self measured studies have slightly bigger numbers 6,4” self measured goes quite well along those studies.

Self reported studies like here on thunders I guess is “pretty reliable”, but is around 1 cm larger mean wise than some of the externally measured surveys. I believe the reason is: Lower EQ, difference in force applied to ruler, self-reporting “round up”.

I believe the studies with measurement done by the researchers staff doesn’t push the ruler as much into the fat pad as you would do yourself and also the EQ is probably also 8 instead for 10.
Also I believe that in self measurements you normally tend to get just the right angle for best measurement and round up which all in all also probably adds 1-3mm all of it because we have so fragile ego’s :-)

The standard deviation is pretty much the same ie. Around 2cm.

When I compare my own measurements I compare with Thunders database. Ie. Mean=16cm, standard deviation=2cm
I’m pretty sure that if I got somebody else to measure my BPEL, it would be around 1cm smaller than my own.. Or at least 5mm, depending on circumstances.
And all of this matches perfectly what I see (or more have seen) in public showers etc. Adjusted for some skewing since smaller guys probably tend to avoid showers compared to larger guys.

Most analyses of the Thunder’s Place stats strip down the used data to a sensible population where outliers are removed entirely from the data set, so the standard deviation is going to be quite low, it’s designed that way. For example currently on the live analysis page, the initial dataset is 12,231 people but only 4,758 people were used in the analysis.

If you didn’t do that you’d end up with one guy who entered a BPEL of ~30” (76cm) - probably by mistake - and lots of other lesser cases skewing the results away from what is normal.

For anyone wondering. .3 to .5 inch gain has been amazing for me and my wife. I know some are here thinking of getting much more but a good gain to start is .3 inches, it converted me to being called in the bedroom. Harder, it feels big, I feel it so deep, he is long, and the best one being when she looked at me straight on and said, I LOVE YOUR D when I hit .5! So my first .3 gain was great for me for like 10 years and .5 was epic for me and I’m very happy PE person. At the moment I am 7 BP and I want to cement these gains. Maybe add .2 but I will listen to my body and see if there is any more juice.

I know I’m about 8 years late - but thank you for reviewing all the data and summarizing it for us.

I wish I would have tracked and documented my progress more closely to share it on Thunders - but alas.
