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)
2008 Starting size: 5.25 BPEL, 5.5 girth, vol. 12.7
2009 Plateau reached 6.5 BPEL, 6.0 girth, vol. 18.6
