Hum, no. Star a will always be a limited substitute for actual racing.

First there are all the uncontrollable variables, such as wind on the day, group v solo, cherry picking short segments etc.

Second, a virtual txt, even if you could control all those variables can never substitute for head to head racing, which is so much more than how many w/kg you can put out for a given segment.

So have fun with Strava, if you enjoy it, but suggest that it's more important than actual race results is absurd imho.

Heck, I doubt that Strava results are even all that predictive of actual race outcomes.
