Jonas wrote what I was going to write re: 1991 Nationals and Worlds. Kerrigan's short program combo was 2T+3T, plus she only had four triples and falls in both programs. (Nationals: 2A fall, 2F step out, 2T+3T, 3S, 3Lz, 2A, 3T; Worlds: 2A, 3F, 3T+3T, 2S fall, 3Lz eked out, 2A, 2S). Jill could match the Nationals content jump for jump, swapping out lutz for flip. I agree that a clean short (even with 3T or 3S) plus repetition of her 1990 Nationals or Worlds program would've been enough for the bronze in Munich, given how poorly Ito skated.
Albertville was such a mess that Jill might've medalled with clean-ish skates. I don't think she'd have been worse than fourth in the short program (and could've been third) with a clean program that had ANY combination. For my money, she'd have been third with 3F+2T, as she did at Sectionals, and not worse than fourth even if she did 3S+2T as she had done earlier in the season.
Kerrigan's free skate was weak, with only four clean triples and nothing harder than 3F, plus three big, messy errors. Her completed clean triples were 3F, Lo, 3S, and 3T with no real combinations (just the huge pop on the end of the 3T). For me, a 4-1/2 triple Jill with only one minor error, e.g., 1990 Nationals or Worlds style performance, would've gone ahead.
So in a best hypothetical, I could see:
Yamaguchi 1-1, 1.5
Ito 5-2, 4.5
Trenary 3-3, 4.5 (or 4 3, 5.0)
Kerrigan 2-4, 5.0
Another interesting hypothetical would be a clean short program but a weak free skate. In that case, Kerrigan might've ended up with silver ahead of Ito.
Yamaguchi 1-1, 1.5
Kerrigan 2-3, 4.0
Ito 5-2, 4.5
Trenary 3-4, 5.5 (or 4-4, 6.0)
