Do we measure all Senior Ladies who competed at Worlds elite level should have all FIVE Different Triples (3A excluded). So if for someone who never has in her life has actually landed a true Lutz should be considered as lacking of Senior Ladies Skill? So automatically deduct the base points?
There is no requirement as to which jumps a senior lady must do in the long program, and only the double axel is required in the short (and two different triples in the short, although which ones are not specified).
It is not true that all senior ladies attempt triple lutzes.
If you look at some of the skaters who don't get past the qualifying rounds at Worlds, who even some who squeak past the short program into the long at Europeans or Four Continents, it's not surprising even now for some of them to be attempting only two or three different triples.
This year Jenny Don won a senior international and placed in the top half at 4Cs with only two. Five years ago Mikkeline Kierkegaard and Lucinda Ruh placed in the top half at Worlds with only three, and in '98 Lenka Kulovana placed respectably with two.
Overall skating quality counts for at least as much as jump content in determining whether a skater is "senior" or not. (Also, of course, age, and the strength of the field in the skater's home country.)
In the mid-90s, it often seemed that many low- to mid-ranked senior ladies would have three triples in their repertoire, and the third (after salchow and toe loop) would often be the lutz, because they could get a higher base mark in the short program by trying it instead of the loop or flip, even if they had little chance of successfully completing any of those three triples.
In the early '90s, skaters with five different triples were rare indeed, and in the '80s, having even one of the harder triples (loop, flip, lutz) was a big deal.
It's now gotten to the point that enough ladies around the world are trying five different triples that in any given year all or almost all of those who make the final round at Worlds will have all five in their repertoire.
But of course they won't necessarily complete all or even any of them successfully in their long programs, and they might pop and not rotate more than a single or double when it counts. Some of them may never have landed a particular triple cleanly in competition ever but continue to include it in hopes of getting partial credit for a reasonable attempt. There are all sorts of things that skaters might do wrong on these attempts, and changing edge on the lutz takeoff, whether severely or just slightly at the last second, is only one of many possible errors.
