You sure it's not just you tired/powerful legs?
Don't thinks so - 2x20s are pretty much bang on usually.
IIRC the calibration value is 7000ish - I gather that's not good.
I'll be doing the test in the link you posted, once I have a known weight / or once I find my luggage scales.
If it's an old-style Powertap then the 'calibration' number is actually the serial number. My Bromton's calibration number is always -6029.
That makes a more sense - the reading itself has never changed.
I'm going to hang a big weight off the pedal some time this week.
