Stats
88.5Kg and 9.5% bf.
The weird thing is that according to my stats history I’ve been heavier before although I’m clearly more muscular now. So I’m guessing my bathroom scale isn’t off and my tape measurement isn’t malfunctioning either. So I’m blaming my skinfold caliper. Not that it’s not working properly but I haven’t been reading and taking measurements properly. The last few months measurements probably have been ok, they seem to stroke with reality and other pointers show the same trend.
Suppose I’m reasonably accurate while performing a Jackson Pollack calculation (3 folds) and make a 1mm error on each fold. At my age this totals to a maximum of 0.9% which means 2 results can differ up to 1.8% or 1.58Kg. A 1mm error might be possible for a tool related error but it’s reasonably safe to assume larger fold will yield larger errors. If I would make a 1mm error on the smallest fold and use this percentage on the larger folds an error in lean mass might run up to 2.3Kg! Ofcourse, this assumes you make all errors on day 1 on the negative side and on day 2 on the positive side, in reality errors will level off more then this but still… Maybe taking an occasional reading is good to gage progress but making exact predictions based on lean mass and fat mass is really pushing it.
