Calibration still off
Posted: Thu May 13, 2021 10:03 am
Hi John,
I originally did a cal ride last year, then had you review and you tweaked it for me around sept. This April I updated the config with new accurate weights of me and my gear but I've been noticing that my power is being reported about 50 watts higher than it should be. The windier and more oblique the angle, the higher the discrepancy seems to be. It also seems that the more power I generate, the bigger the discrepancy i.e. 200ish watts reports as 230-240, 300 watts repots as 375-390.
This is obviously in general terms- I base this all on the last 5000 miles of indoor Zwifting on a Tacx Neo since November. I'm pretty used to the feel of wattage at various levels.
This ride I'm attaching from yesterday was an easy ride, I only exerted a bit when I turned south and caught the tailwind. The power reported is too high for the feel and for the heart rate.
Can you please take a look? Should I scrap it all and do a new fresh calibration ride? I thought it was always doing that automatically within 90 seconds or so of starting out...
Thanks,
Biff
