HRM - how often do you change weight?

Ecce_Signum

Probably been asked before but how often do you guys change your weight when using your HRM? I changed mine today after losing 12lbs and was used to a one hour 'run' burning 500 calories (MFP has is as 621).

With my current weight plugged in I went out for 45 mins today and burnt 243 cals! (324/h). I knew as you lost weight you burnt less calories but never imagined it was this much - I've been drinking back my exercise cals in alcohol so been having at least 1 can a night too many lol.
