I’ve tried two runs at Jon’s Mix which has some 10 second intervals at max power and it hasn’t gone so well for me. I feel like a short person being told to stand up after I’m already standing. :)
I’m strongly typed as a time trialist with slow twitch muscle fiber. I’m not making excuses here but my max 10 seconds is a pretty pathetic 700w and not even very reliable at that. As a consequence I always FAIL the max power target (which to be honest, I have no idea what the target really is because no target value is displayed). I do the interval and the whole time the system just tells me to increase power. In my best impression of Scottie from Star Trek possible, “I’m givin’ it everything she’s got, cap’n!”
Okay, enough sulking about it. What I think may be necessary here is to replace max with some specific value or even better to read it from past performances. If we take our best 5 seconds power then our maximum is probably within 10% of that. Either way, instead of saying to do MAX I would benefit from having the number shown.
On another matter it can be pretty hard to go from a sedate 160w to puke-hard watts instantly but in my experiments with ERG mode it is neigh-impossible. I use a CompuTrainer and it was like hitting a wall and my cadence fell to 25 RPM within seconds. Sim mode is better but I still can’t hit the theoretical max value.
