As the letter frames are generated randomly from a scrabble set, I can play along myself. I personally achieved a modest score of 114. I began well with a decent spare on frame 1 but frame 2 was a bit of a horror show. On both frames 4 and 7 I made judicious use of the blank to get spares. On frame 5 I only scored 5+4 but there is a scrabble-legal ten letter word available for a strike: DETOXICANT. I didn’t get that without help, so can’t fairly claim it for my own score. However I did score over 100 so I can be happy with my performance.
