Doing a double axel in both directions is crazy impressive though... I wonder if the computer would have to count that as a 2A+2A+C combination instead of a 2A+2A+S sequence?
I'm sure it would be counted either as a sequence or as a two separate jump elements, and therefore the skater would get much less credit for it than it deserves.
I'd like to see a rule that would reward that kind of thing appropriately.
For a combination, I'd propose something like an additional 0.5 per half revolution of the bad-direction jump added to the base value of the element.
For jump sequences, maybe allow a single step or edge change without splitting the sequence into two separate elements and also add a bonus as above.
This would also be better if sequences got full credit and combinations got bonuses at least for the second jump.
