This is the thing....there are very few 'professionals' that take bf% with skin calipers. Unless you have pinched a couple hundred people, then there is no way you can trust anybody. Those people that took your measurements are not 'professionals.' This is clearly visible. I have done many pinches over the years and I would not even say i'm close to being great at it to consider myself a 'professional.'
Don't let these people get you down. Who knows, they could have also been just hating on you (jealousy). Maybe not though. The important thing is to gauge how you visibly look through appearance...ie pictures and mirror.
If I were you, i'd go to the Women's board and do a search under a very smart, and well trained expert, under the name Hybrid1 or Wilson6. He wrote a lot of awesome info regarding BF% measuring. I'd can say with good faith that he was a real professional in this area. Hopefully something comes up, as I don't believe he posts here anymore....unless he uses a different handle now.
Good luck man!
