Before I purchased my PowerTap pedals I did some research on here to see how they were. Everyone pretty much loves them, but there was a thread about calibration. It talked about when new, the calibration number was single digits and over time it would climb up into the 40s and 50s (maybe more, can't exactly remember).
My question is what difference does the calibration make? I only ride outside as I don't have a trainer. I installed them this week and calibrated them (double sided) which were 55 and 56. Today they were 44 and 45.
Since I'm not out comparing my power numbers to anyone because mine are so low, I thought the results would be good for training and racing, regardless of the number. So, if my ftp test said 175 I don't really care if that exactly correct. I only care if it doesn't change day-to-day because of the calibration.
If the calibration changes from 55 to 44, does that produce a different reading on the power when riding? If so, is the power reading higher or lower when calibration is 44 instead of 55? If different, is it a percentage (20% in this example) or an actual watt number (10 watts different)?
TIA
Not a coach. Not a FOP Tri/swimmer/biker/runner. Barely a MOP AGer.
But I'm learning and making progress.
