Powermeters comparison in the hill

[Texano999]

Dear
I have hot powerpod and powertap model in my bike and i made a comparison at hill.
I am sure about my powertap calibration; i noticed that in the hill Measures are consistent but powerpopod give me 10-20 watt more costantly. I check my weight in isaac and was righe; then i decrease my weight and i have very close values.
Point is that my weight me and bike is not so low ! Can you explain Why?

thanks, now it is fine it was my mistake on the pound kilo conversion.

i calibrate completely my powerpod same figures in hill little different on land due to wind (10 watt) on 30 sec power but it is fine-
after check calibration i have got wind scaling 1.2 aero 0,403 with CDA 0.336

seems good?

how can attach the file here?
