The fact you said you like standing the whole time on a different thread would suggest you are a good low inertia, power rider. It is a proven fact that 300w at 100% is exactly the same speed in the game as 300w at 0%. It’s solely feel.
I hate climbing, and that’s why I dislike 100% as it makes the deadspot in the pedal stroke more pronounced (like in real life) and I struggle to hold the same power as I can on the flat. But that’s why you have to use 100% on an official vEveresting attempt, as it’s necessary to simulate the challenge of the lower inertia when climbing.
If you are faster up the Alpe at 100%. then you must have to make numerous gear shifts up and down through the hairpins, and surely must struggle to hold steady power (which conceptually is always going to be the fastest way up, rather than surging)?
EDIT:
Save a separate post! Do you actually use the trainer power numbers? I don’t. I can’t see any reason why people would if they already have power meters. This is a side issue, as clearly if they’re claiming accuracy then ideally they should be, and it’s certainly of relevance for those that don’t have a power meter, but I only ever use the numbers from my power meter as I want everything to be comparable to outside data wise.
