Your best fit depends on what you're trying to do

A commuter who wants to arrive un-aching, a randonneur chasing all-day comfort, and a time-trialist chasing watts-per-drag do not share one ideal position.

That's why OpenBikeFit asks for your discipline and goal up front, and why it has explicit optimization modes. The default protects comfort and safety; you can opt into performance or aero, and you'll see the tradeoffs each time.

Changing your goal changes the advice. That's a feature, not an inconsistency.
