Offhand, the gym I'm currently at doesn't have any L8's as they all left or retired last summer. I can't really remember what the L8's at my old gym used to do and I haven't made an optional meet this spring ( I'm going next week and told my old girls I'd go watch State 7-9. ) as I still hang out at that gym and workout there.
If you download Gymquest and run the study aid, you can select L8 and beam and see what skills are listed. It would be better to read the L8 JO code if you have access to it.

Saltos could be front or back flip or gainer to the side. Front Layout and twisting backs are worth a B instead of the ones before that are worth an A.
Acro: Back Walkover-Back handspring( w/ step out ). Front handspring should count as an element with flight.
As for deductions, gymquest show all those as will the JO code book.
