Mathman, you beat me to it on Michelle's competition triple-triple statistics. I thought it was around 11.
To respond to your original question, IMO she hasn't waited too long. She'll be giving her first COP version of the program at her first COP competition. She has said several times that Bolero is a work in progress; plus there were the reports of her testing out the COP aspects of the program both with RA and CD and Lakernik (sp?). I think Michelle has always been true to her word, so I have no reason to doubt what she's said thus far.
I have thought for some time that she is on sort of a two-year plan. Last year she started by going to Arutunian to work on her jumps and I for one have seen improvements. Again, the reports we have received have her working on several triple-triples. This year she's adding the COP details and decided to really challenge herself by using Bolero and CD. By doing this IMO she has kept herself motivated and that's good.
I really don't think it's fair to say that Michelle has refused to get the message that triple-triples are essential. The statistics show she has done them in competition. I think for the most part she has competed intelligently where triple-triples are concerned, all the while keeping in mind her current and future health.
I've chosen to think of Bolero as her "senior thesis" if you will. She's decided to tackle this music, with the T&D legend behind it, while jumping into the new scoring system. IMO if she lays down the performance of it that she's been working towards at Worlds, she'll probably pick something else for next season, and in that case, I think she should, to keep herself motivated (that program would be her "doctoral dissertation", LOL). Or, if she feels Bolero is not quite there yet, she may keep it for another season. I'm going to reserve my decision on whether I really like the program until after I see the World's version.
IMO, the pressure of attempting to tie Maribel's record, plus using a 6.0 version of Bolero, caused the glitches in her performance at Nationals. You could tell she was dissapointed with it, but it was enough that night, and what an accomplishment, to tie that record!
I think she's set up nicely to debut her two COP programs at Worlds. Most of the pressure should be on Irina and Shizuka, she won't have the expectations of the home crowd weighing on her, and she should just go unleash those COP programs she's been keeping under wraps!
