I’m routinely getting results of ~ 2% or less disparity between my left-only 4iiii crank and Kickr when both calibrated. That’s pretty good (unless I have a massive leg imbalance of course )
Yep, this is what I used to experience until all hell broke loose. The core is consistently 10-15% high. For what it’s worth, the last time I was on one of the watt bikes in my local gym (pre-covid) I was very close to 50/50 leg balance maybe ~1% swing to a right dominance. Certainly not enough to explain the above.
