It would be energy draining, but I wonder why none of them take advantage of attempting 8 triples if it is allowed/possible to do so. The most I've ever seen attempted is 7 triples by a lady.
Because under the rules, one would need a 3ax AND a 3/3, 2ax/3 or 3/3 sequence in order to achieve an 8 triple program. Very few women have the 3ax. Mao is probably the only one who can come close.
Kimmie at one time was rumored to be trying for it (3ax, 3flip/3toe, 3lutz/3toe, 3lutz, 3 salchow, 3loop).
