@el6 I definitely want people to draw their own conclusions from the data, but I think that it is incorrect to only look at the total
Girth gains of one over the other.
It should be taken into consideration that those who got 30% received an avg of 6 cc more than those receing 10%. Calculating this difference back into the 10% numbers will reduce the variance. Granted, even after adjustment 30% numbers do look to be greater.
For example, if you adjust irishfan down by 6cc, his gain would drop from .75\" to about .59\"
Looking at hulk, if you decreased him down by 6cc, his gains would show to be around .74\" from .98\"
Likewise, if you added those 6cc to pmmaalltheway, his gains would theoretically rise from .63\" to .86\"
I wish I could account for the variance in cc received.
