Along with my ipod nano and my HRM this has been my best fitness purchase.
Even with a 10% inaccuracy, say in both the GWF and my calorie counting, I can still have a noticeable deficit.
Actually, that would be a fun calculation to plug into Excel. I love stuff like that.
It's been exactly 2 weeks for me and 5 lbs gone, none of which were quick "start of diet" losses.
I am seeing a possible innaccuracy in my gym cardio as I use the ArcTrainer (no arms.) The first workout I did with the GWF and the ArcTrainer appeared within 10 calories of my Polar HRM. Yesterday I did 35 min on the ArcTrainer with about a 100 calorie difference. But, I will admit, I was not using the display, and just going off finding that 35 min of activity on the chart.
I will try it again using the "trip" on the display. If I still have a discrepency, I will try the leg option. I have yet to try plugging in data as "edit off body." That's another option.
I don't need exact numbers, but I like knowing I'm in a deficit.
