This isn't the first time it has happened. I should have learned to do the zeroing a good five minutes before the start of a race, but I didnt.
What happened was that I unclipped and performed the zeroing on my Garmin (the auto-zero function on my PM was turned off). Everything seemed okay, except at the start of the race, I was pedaling pretty hard, but Zwift showed me doing only ~300 W, whereas Garmin showed me doing ~390 W. I wonder what could have made Zwift apply an erroneous offset.
As for the race, even when I stopped pedaling, there was still a pretty big discrepancy, and I had to restart the program. When I did, the numbers on Garmin matched up to those on Zwift.
Anyone knows what might have caused this? Previously, I had situations where after the zeroing, Zwift would apply a ridiculous offset so that it showed my doing 0 W, despite my pedaling at a good clip (~200 W or so). This one kinda slipped by me, b/c the difference wasn't as drastic when I was pedaling at 200 W.
