I bought new direct drive trainer (tacx flux), so now when using Zwift, I have an option to use either power meter as power source or actual trainer.. I have tried both setups but both cons and pros
1) actually trainer as power source.
pro: during intervals power line is 10 times smoother
con: actual numbers are 10-15% higher than outside while i read most people have them lower in indoors vs outdoors
2) use power meter (4iii left crank) as cadence and power reading source
pro: same instrument measures power indoor and outdoor so power profile looks similar
con: during intervals lets say 10 min one, actual power readings are all over the place (10 min @ 200w i have seen 175 and 225 pretty often on 3sec avg) with the same cadence +-2rpm... I would think it is not that big deal during 10mins but if I do 3min @ 110% 3 min @95% 3 times there is not much difference between 110 and 95
It feels like trainer is trying to catch every second. I am not not sure if it is the problem of Bluetooth signal processing. read->send to laptop (Zwift)->send info to trainer-> trainer corrects resistance->repeat
Has anybody "played with this"? which setup would you use?
