Do they slow down after beginning to square off? Are they fastest in pristine condition, or after a short break-in period? Surely someone has measued this.

Since one of the factors influencing rolling resistance is tread thickness, worn tires typically have lower resistance than new…even after “squaring off”.
Yep, it sure does. The fastest tire is the one that’s ready to go into the garbage. Whether or not it’s worth is up to you, though.
With that said, AFM’s chart on BTR seems to demonstrate that for best results you should at least get some miles on the tires first.
Hmm…interesting. Why, then, would people “save” their race tires for race day, and not run well-worn low RR tires?
Perhaps I should send my ProRace 2’s to a roadie for seasoning before the next race.

Most likely because their “race” tires, if they are GOOD race tires, already have thin treads. Riding around on them during training just wears them out faster and makes them more likely to be ruined prior to the event.
A “well worn” training tire can still be slower than a brand new “race” tire since tread thickness is only ONE of the factors affecting rolling resistance.
