Okay, yeah, it's a brag post and a Sim opponent, but the second half my BYU team threw together last night against Colorado St. might be the best one I've had a team compile in this game. 31-for-41 from the floor over the final 20 minutes.

I've had teams hit in the high 60s for shooting percentage for a half. Can't remember one finishing in the 70+ range though.
Feel free to post your own 20 (or 40) minutes of carnage as well...
