Interesting point about the feedback under 6.0. But it seems to me (and it's just a vague recollection) that we did see a lot of correct triple lutzes back in the day... Tonya, and Midori and Nancy and Oksana.. So there must have been some motivation to get it right?
I have wondered - and this is just a question - if the flutzing and Uring simply became more common as the jumps got more difficult for the women. This is not to say that a correct and fully rotated triple lutz-triple toe is not a reasonable goal... but as more ladies upped their technique I wonder if many of the less gifted jumpers were tempted to shrug off technique just to keep up. You know - maybe a lady just couldn't seem to achieve an outside edge triple lutz in practice or a fully rotated triple-whatever - and just decided to be satisfied with the flutz or a URed 3-3 because she felt that is what she had to do be remotely competitive...
Essentially, I think that's true.
My theory is:
In the 1980s, if you had a really big, good double lutz you would try to learn the triple. Very few ladies succeeded.
If the lutz gave you trouble, you didn't bother trying the triple. If it gave you a lot of trouble and you had easier triples, a good double axel, and good double flip and loop, maybe you filled up your program with those jumps and didn't even bother including double lutzes, except in years when it was required in the short program.
As of 1990-91, when figures were eliminated, there were maybe 20 ladies in the world, plus or minus, who could do triple lutz, because they were among the few who had had good doubles in the 1980s and made the effort to learn the triple and were successful in that effort. (In addition to the big jumpers named above, that also included Kristi Yamaguchi who didn't have the greatest height or strongest takeoff edge on her lutz but was able to land the triple consistently because of good in-air technique.)
Jumps were now becoming the deciding factor in who won competitions. And the skaters were no longer spending hours a day perfecting their edges on figure eights any more.
The top ladies in the world in the immediate post-figures era were doing triple lutzes, and including difficult jumps was the way to get to the top. So getting all the triples up to lutz became the goal for skaters who aspired to senior international success. Many of the ambitious juniors ca. 1991 and 92 were trying it, and by 1993 they were moving up to seniors. By the mid-1990s, five different triples were expected for international senior and even junior medals.
So the motivation was there to try to get those jumps, or a reasonable facsimile thereof, no matter what, even if one's double lutz technique was iffy. It was considered more valuable to do a so-so triple lutz in the short program than a decent loop or salchow. It was more valuable to plan five different triples, seven triples total with repeats, in the long program than to make sure the takeoffs were perfect on all those triples.
In the 1980s only great lutzers did triple lutzes. In the 1990s, anyone who could rotate three times in the air was trying triple lutzes. Some did it right and many did it wrong.
