Ok, I used your site to calculate my BF today. (I had a trainer at the gym
take the measurements with the gym's metal calipers.) But...I have
discrepancies.

Also, I only took each measurement once, and use that number for the three
values. Don't know if that's a big deal. We were pressed for time.

With the 7 point method, I got 14.88%. Using the same numbers with the 3
point calculation, I got 11.93%. I'm assuming the 7 point is the more
accurate and I really am a fat [censored]? Do you normally have that much of a
difference.

Also, the trainer thought for sure that the 7 point took a pinch on the
calf. As she remembered it anyway. Are there different methods? If so,
why did you choose this one?

Larry I use Jackson-Pollock 3 and 7 site, the Pollock 3 site and
something called "P-9" and it is only the latter that takes the calf.

Everybody carries their fat in different places. It could also be
measurement error. That's one of the reasons that three skinfolds at
each site is recommended.

Nope. That's the Parillo nine-site.

Several.

The Jackson-Pollock methods[1] are generally considered to be the most
reliable overall. I have a reprint of the journal article if you'd
like to see it. I also have a listing of nine different formula that
use different combinations of skinfold sites.

No, I don't need the article. I'll take your word for it.

Given that I've been bulking for the last three months and gained 10 lbs, I
actually figured I would have a higher BF. That was a pleasant surprise.
I'll cut back down to 10%, then do another cycle.

Thanks John.
