Ah, you beat me to it Demon Dash. I’ve just been testing some stuff out myself. It turns out, that if the opponent is always crouching (huge assumption, true) almost any character can kill in under 10 seconds, many of them in under six.
The training mode timer starts at 60.99 and I achieve roughly the following results on crouching characters.
53 seconds left. Ryu. J.HP, HP, Joudan (MK). Then HP, Shoryuken (HP), SA2, HK.
54 seconds left. Urien. SA1. Can’t remember the details.
55 seconds left. Ken. J.HK, C.MK, SA2. Then crossup J.MK, MP, HP, Shoryuken (LP), Kara Shoryuken (LP) (Note I can’t actually land the Kara, I suck, hehe).
56 seconds left. Q. J.HP, MK, Dash Punch a few times (IIRC).
56 seconds left. Akuma J.HK, HK then J.HK, HK SGS. (vs Dudley)
57 seconds left Akuma J.HK, HK then H.HK HK dash KKZ. (vs Dudley)
57 seconds left Makoto (assumes massive luck) QCF HP, QCF MP, SA3 F + HP, F + HP, F + HP.
58 seconds left Makoto (assumes massive luck) QCF HP, QCF MP, SA3 F + HP, F + HP + HP + HP (vs Akuma).
Please don’t rely on these exact figures. I just spent a few hours messing around and jotted this lot down from memory.
