Any measurement is an estimate, so what is the best way to record bodyfat% besides doing hydrostatic weighing. Basically, when it comes to down to the average joe, is it better to get one of those new scales or use calipers?</div>
You have to understand the quality fo the measurement.
Autopsy is the best, but not useful
UWW is just as problematic due the assumptions it is based on
Total body fat content in a group of professional football players
.Adams J, Mottola M, Bagnall KM, McFadden KD.
A hydrostatic weighing method coupled with a closed-circuit helium dilution technique was applied to twenty-nine professional football players of a successful Canadian Football team to obtain body density values. From these results, it was hoped that values for percent body fat could be calculated for each player using Siri's (1956) formula. Unfortunately, the values for body density were so high
that for some players negative values for percent body fat were obtained. It has been suggested that these results reflect large skeletal deposits in response to the heavy exercise routines undertaken by the players. Skinfold measurements of the players suggest that there are more fat deposits than their body density values indicate. This casts serious doubt on the use of Siri's (1956) formula with the extremes of body form found in the population and also suggests restricted use of equations based on skinfold measurements for estimating body fat percent.
the scales require frequent and consistent use, and the calipers have a relatively wide range of error as well, which can get better with consistent use, but still can be completely annoying. Measurement points need to be measured, not looked at and guessed.
And even then, track the skinfold distance or the sum of skinfolds. Converting it into BF% is pretty much worthless.
