specifically, i was trying to investigate 1) the power difference between the kickr and vectors, 2) the effect of kickr variables (erg mode, readings before vs after spindown, and warm vs cool kickr) and 3) the effect of drivetrain variables (lube, x-chain). i have 2 sets of vectors but i only used one set for the test. fwiw, both sets read the exact same as tested vs my friend's quarq but i cant remember the diff between the quarq and vectors.
initial takeaways
kickr needs to warm up - less accurate when starting (trial 1)
little difference with lube or x-chain, though the trial immediately after lube was ~1% closer to vectors before going back for sub subsequent trials
erg brings kickr closer to vectors
kickr watts expected lower due to drivetrain losses but differences were variable between 6.9% (first trial on cool kickr before warmed up) and 2.9% when the kickr was in erg mode
kickr likely less accurate than vectors due to power smoothing and measurement method
