I'm not disputing the question, but wondering why bother generating any data at all if nothing is real?
i think we can all agree that neither would be correct. but my point really was why bother to compare two completely different algorithms. from Strava:
Strava can estimates power using information about an athlete's weight, speed, and elevation change.

strava does not take road conditions into account.
Zwift may actually be more accurate since it is based on particular trainers:

neither takes wind or temperature into account (guess zwift needn't do so). i don't know how temperature would affect this but i seem to recall others here on BF making that claim.
i do think it is fair to compare one vs a real ride though.
i'd love to know what my power numbers are in real life but a meter is not in the budget for me. i still enjoy my rides regardless.
