Data on PE gains from TP database

I have done a little more data analysis with the TP database. I was interested in how much size TP users were gaining. Again, I started with the raw TP database of over 13,000 measurements entered. I look for everyone who has two or more measurements entered. I threw away any obvious bad data (EL over 11” or less than 2.5 “ etc) I take just the first and last measurement entered and compare them. I also eliminated any where the time between first and last was less than 30 days.

What I have here is a scatter plot of length gains vs girth gains. Note that some reported loosing length or girth, so there are some points below zero. Overall though I think you can see that the average TP member has seen significant gains.

The average length gain is 0.7” or about 12%
The average girth gain is 0.32” or about 7%
The average volume gain is 3.36 cu.in. or about 29%

Wow, volume is where it’s at! The average TP member has added almost 30% to his dick mass!

P.S. Standard deviation is useless with this type of data (too near origin on graph)

Good analysis. Pity TP cannot publish this as scientific proof that PE works

Great work Wrightman!

I did more or less the same thing, but I guess I was a bit more strict with the filtering (f.e. I removed inconsistent entries and people with unrealistic gains or, in other words, too big of a difference between starting and ending stats, etc.).
It’s nice to see how close our averages are though, mine being a little lower, probably because of the stricter filtering. :)

Quiet. PE doesn’t work. It’s all a hoax. Now carry on. Nothing to see here.

WTF, I didn’t know there were several cases with loses in both lenght and girth…

Great and hard job again

Wondering if it was easy enough to colour code to the method recorded.

Not sure that is captured simply enough in db? Manual vs mechanical and/or both. Just a thought.

The losses were most probably the result of:
a) Inconsistent measuring
b) Heavy overworking
c) Increased fat pad

It’s highly unlikely for a PE’er to have losses that are actual losses and actually do stay cemented.
There are probably a few cases that are actually genuine, but I’m sure there’s an explanation for that too. :)

boardlogon, I didn’t quite get that. Could you try again?

Thanks for putting this together.

Of all the dots on the chart, is there any info on method used by the person logging the data.

If you download the TP PE database, you can see all the data, then pull up the profile for any user youre interested in, then see if they have posted info on their routine. It would be very tedious. Another way is to just search the threads for postings that talk about gains and the routines. Anyone know a better way?

~ Nice work.

This needs to be stickied in the Newbie Forum. THunderSS or mods who can do this, I think it would be a good idea.
