The one shown in TBs video obviously, since that's what I was referring to with the 1 frame links. Do it as he did it, with the mix-up as close to 1 frame as possible, if your execution is trash and you fuck up the AI recording, just redo the AI and get it close as possible, no cop-outs. Me and SaltShaker mention this because Dink did the exact opposite, and deliberately slowed it down and injected a bunch of gaps. Record it right and then block it even twice out of a 5 AI laps of it without hitting the reset button in training mode. Then try do it against a real opponent who will be adjusting the timing of the tiny link even unintentionally.
I think you need to take some of your own advice about spending more than 10 minutes in practice mode mate.
