Newton reading very low all of a sudden

Hi, for the last 3 weeks or so my Newton has been pretty useless. It started reading about 100-200W lower than it had been and is inconsistent. I have tried a re-cal twice with no success.
Any ideas?
Thanks
Dan

Hello danhulbert,
I just took a quick look at your file and your negative CRR value jumped out at me. That cannot be correct.

Russ

Sorry,
I can't resist qualifying my post, cannot be unless you have warp drive wheels
From your advances stats:
Rolling -225 -119.9 -0 W
CdA: 0.373 m^2; Crr: -0.0156
Now if you tweek your CRR to .005 (typical)
you get this in advanced stats:
Power 0 259.1 1084 W
Rolling 0 38.4 72 W
CdA: 0.373 m^2; Crr: 0.0050
Regards,
Russ

Thanks Russ,
Will update it and give it a go... warp wheels were in the shed along with the warp legs
