That's possible that it could turn a lower radius, but it would lose angles because of its higher wing loading, I doubt its ROT can compete at that speed. Even though its real-life ROT is just as good but at somewhat higher speed. If going to low radius doesn't get it a quick kill, it's in a bad position. Better to let the slow plane make that mistake, then pound it from above when it's too slow to climb. A Spifire going around in slow flat circles is a welcome sight to any fast plane

I haven't seen EM charts for yak-3, maybe I will try to find one.

I got bored and drew a couple diagrams about haitch's questions, next time I'm bored I'll scan and post them.
