In light of all this, I have given up on finding a fixed, absolute number. Beyond the average daily variability, I look to see if my number goes up or goes down. Down = good. Up = bad.
If you are really into keeping track of your numbers then pick a few tools and stick with them, measuring at the same time every day, day-in-day-out for at least a month (30 samples). Only then will you know if that new diet is paying off or if your new arms routine is really adding mass.
