How about pre - Zayak rule?
I'm sure Elaine did 7 triple skates a few times, possibly at 80 worlds, 81 nationals, and 81 worlds.
Also, Sanda Dubravcic from Yugoslavia did an 8 triple program IIRC in the late 70s / early 80s.
What about Sarah Hughes.
I think she may have done them at 99 Worlds, 01 Worlds and the 02 OG.
