So this is an interesting case.
On the one hand, if going by frame count alone, this is indeed faster than
the currently published TAS.
On the other hand, however, the faster time is achieved by
timing out the fight against Heihachi. This in turn means that, if we count in post-input gameplay (the ~35 seconds after Nina executed her last move), this movie is
slower than the currently published TAS.
There has been at least one precedent (Magician Lord, though the three minute waiting period on the
previously published TAS produced the opposite effect of killing the pacing, whereas it's not quite the case here, since there are people who seem to like it).
To me, this TAS is slower gameplay-wise, simply because the fight is still going (and thus counts as gameplay) after Nina executes her last move. Not to mention the ending sequence is reached slower due to the timeout.
