I’ve got multiple years on Stages gen3 and SRAM Force and Red. At low recovery watts, under 100W, I see left/right imbalance. Otherwise 48-52% which is basically 50/50, and anything tempo and above it’s always 50/50. So it was a surprise to see RS200 start around 41/59 split and after a handful of rides I’m at 47/53 which still seems off a bit. But overall the accuracy is good enough.
Support also had me reset the platform offset (edit: reset install angles) on my 530. Odd that isn’t in GC Mobile.
