Why? Is it going to influence a change? Or is it just an intellectual exercise for you? I have a number of disappointments, that are liveable as they are consistent. And being a zwift jersey winner is not a goal.
I have a lemond revolution trainer. Its fan based so takes a little to generate watts. But it doesn’t take 10 seconds. If I jump on a sprint, I may be 50 yards in before my watts exceed 300.
My secondary speed measure is 25 + mph, so the lemonsd is recognizing my acceleration, but not zwift. Eventually I’m holding 1000+ for 10 seconds, but am exhausted when I get there. On the road with my powertap wheel, thats about 400+ short. And I get there much quicker.
So wah for me, however I suspect the calibration is linear on the lemond. Instead of with an upcurve. I provided a power curve which I found on line, and I can ‘feel’ its not the same as the zwift calibration. How do I know? I don’t, but its consistent, so I can live with it. I have the new wattbox on order, which should change the game in that I’ll get a lemond calibration for the trainer.
And then I find that unless you are not on a kickr you get capped at 1200. No issue cos I’m only pushing just over 1100 at this time. And its certainly better than when I was capped at 400 for having a ‘dumb’ trainer.
As it is, I’d proabably get a more accurate ‘game’ on trainer road as they have it set up for the measures and nothing else. However I like the view. Even if I am hammering at 25 + mph up a 3 % grade and the zwift calibration is crediting me with 4 mph. So how do I know? Cos on the weekends I ride much hillyer terrain for a much faster result.
Now you may say its online, and its all relative. And it is. But its fun and consistent. And only to get me to outdoors while I am rehabbing my back. And don’t get me started on the downhill…
