Hi Alex,
I just retested the following:
(Kickr5 current iPad App)
FreeRide Mode small chainring middle of cassette:
up to 29% the resistance does not change
about 80Watts at cadence 80 from 15 to 29% resistance
at 30% resistance the power jumps to 180Watt at same cadence/gearing
also suggestion: resistance should “memorize” last setting, instead of going back to the default 15%
hope this helps!
