OK, one more question.

In the short program, suppose you plan 3L/2T for your combination, then 2A and 3F. If you have a wonky landing on your Lutz and omit the double, can you tack a 2T onto your flip instead?
You could. However, you would need to have steps or other skating moves preceding the 3L, or else there should be additional GOE reductions on that move for not having the required preceding steps before the solo jump. Also take into account whether you're likely to get a lower GOE on the flip combination than you would on a solo flip.
And one more.

In the short program, can you do 3Lz, 2A+2T, and 3F for your three jumping passes?
No. The short program requires a solo double axel (double or triple for senior men; single or double for novice and intermediate in the US at least).
Basic short program jump requirements:
1. solo axel
2. jump immediately preceded by connecting steps and/or other comparable free skating movements
3. two-jump combination
How many revolutions are allowed or required vary by level and sex, and the takeoff for #2 is specified each year, alternating among loop, flip, and lutz (choice of double or triple), for juniors.
And you can't repeat the same jump in two different elements -- the only time you could do the same jump twice in a short program would be if you did two toe loops or two loops (double or triple depending on level) in the combo.
So if you want to do an axel for #3, you need to do an axel with a different number of revolutions for #1.
The way the rules are set up now, you would pretty much never see 2A-2T combo in the short program. For juniors and for senior ladies it would mean repeating the 2A. For seniors and for junior men, double-double combos. So not legal.
2A-2T and solo 1A would be legal at novice and intermediate (and was what the top intermediates used to do until last year when they were allowed to do solo 2A), but it would be more valuable to do solo 2A and another double-double combo, or triple-double combo at novice if you've got one.
