Again , the difficulty of Charlottes under new rules is: can't be on flat, AND to count as a position , it must be preceded by change of foot + direction + edge, like any other spiral position. Anything less than that, and it's just a "difficult variation", if I understand the rules correctly.
What's harder about spiral sequences under the new compared to last year is that only the first three positions will count toward level features. It used to be that skaters would do four or five different positions to try to accumulate four features. Now they'll have to get them done more efficiently to achieve level 4.
And there doesn't need to be a change of foot and direction and edge all at the same time. In fact, according to the explanations in the latest communication, if you change two or three of those at the same time you'll still only get credit for one more position and may not get credit for a difficult change. But if you just change the body position without changing foot or edge or skating direction or changing whether the free leg is forward, side, or behind, it seems that that will all count as one "position" but could include changing between a difficult and a non-difficult variation of the same position.
So it's going to be challenging for anybody to build up the speed to do Charlotte as the 2nd or 3rd position. (not sure, but i think only one foot-pump is allowed between positions??).
No, there's no such requirement. Skaters can take several steps between spiral positions and can include turns, half jumps, brief spread eagles or Ina Bauers. The only catch is that any time spent not in spiral position between positions takes away from the time spent in spirals, and a minimum percentage of the time needs to be spent in spiral position to avoid reductions in the GOE.
So something like this would qualify for level 4 (now that back inside edge is no longer required for the first feature):
Left forward inside-to-outside change of edge in a difficult position (e.g., Biellmann or Y spiral) held 3 seconds before and after the change (that's two features, change of edge plus difficult variation, and two positions forward on the left foot, using both edges, toward the first feature)
RFI mohawk, and then a couple of back crossovers (change foot to falling leaf, RFI mohawk, back crossover, or back double three instead of the falling leaf and second mohawk, and then just one crossover) to
Right back outside Charlotte (second difficult variation on the other foot for yet another feature, and completing the feature one requirements by using the other foot and a backward edge)
Or for a forward Charlotte, start the sequence with a backward change of edge in difficult position, then take a few steps/strokes w/ or w/o turns into the forward Charlotte on the other foot
Also, some skaters who had been trying for level 4 with four separate features over four or five positions may now just stick to level 3 and try for higher GOEs
I'm thinking SOMEBODY will try the COE charlotte though, because of the aforementioned, all-season-long 2 point bonus.
I doubt that would be considered innovative enough for the bonus, since it's just combining two skills that are already well established.
