Absolutely.

This past winter, had a guy who helicopters the ball and drifts across the approach throw a 278 and something in the 620s. He made too many wrong mistakes.

I've seen many players get on a roll a few times and have stellar nights.

I don't see this being any different than a 190 ave throwing a 800+ series. Its 200+ pins over average
