I think part of the problem with that is that a skater has a limited amount of time in which to complete x-number of elements. And even within the spiral sequence, there are so many requirements to get the sequence to a high level. There really isn't time to "take the time to do a spiral properly and make it look graceful." You can't just do what goes with the music, because it might not meet the level 3 or 4 requirements. And "taking time" takes time away from the other required elements. So even though a phrase of music might suggest holding one spiral position for 5 or 6 seconds, a skater cuts it down to the minimum requirement of 3 seconds to get it over with and move on to the next move.
Exactly. Also, for a little perspective, go back and look at just about any program from 6.0 days and you'll see that most skaters weren't holding their spirals for more than a second or two. This season you can expect to see almost everyone holding one position for 6 seconds, which is a loooooong time. (Due to the rule changes, the only way to get a level 4 without holding one position for 6 seconds is to have a full split unsupported spiral, and there just aren't many skaters with the strength and flexibility to do that).
BTW, I agree with mskater that it would be nice to have a moves-in-the-field sequence that allows spread eagles, ina bauers, etc. rather than just spirals. I'm guessing the reason they don't is because it might be more complicated to score (?).
I posted a thread about spirals looking for support that Spirals at the Senior Level are no big deal.
If they were no big deal, we would never see mistakes on them. But we do, even at world level (Miki Ando, Carolina Kostner, etc.).
The bottom line on all this, and it's not just for me, is that it is a basic move, and any skater who can not do basic moves, well......
Saying a spiral is a basic move is like saying a spin is a basic move. Yes, it IS a basic move, but are you talking about a simple one foot upright spin, or are you talking about a level 4 flying combination spin with change of foot? In the same way, you can't compare the simple flat forward spirals on the Preliminary MIF test with a level 4 spiral sequence.
As several people have already pointed out, a lot of the men have trouble doing them well, and these men had to do spirals on both feet, going both directions and on both edges to pass their MIF tests. And yet, most still do them poorly, even if they are part of a pairs team and actually work on them regularly.
And not all of the women/girls can do them "just because they're girls" either. I spend 30-45 minutes stretching after every skating practice just to enable me to do my spirals. And, as mskater pointed out, the balance gets a whole lot trickier when you need to go from a deep inside edge to a deep outside edge in less than 1 meter and when you have to create the tension and balance required for a catch foot spiral with foot above head level. If you think it's easy, try it.
