I have an Elite Direto that supports erg mode. I love it for aerobic work but find that on VO2 intervals it fluctuates enough to put me “over the top.” I can carefully control my efforts and stay right on target in resistance, but in erg it floats around more and 10 seconds at 20 watts above my target is often enough to be the difference between completing a hard set and not. I just don’t even bother with erg on challenging workouts anymore.
My question is: do people find this to be the case on trainers that aren’t the Direto? Would a higher end smart trainer be any better at keeping the erg targets spot on or is it just the nature of the beast in erg?
And as a side note: my resistance efforts stay very close to the target TSS and IF, it’s not that I’m slacking on them.
