Looking through older videos of theirs to compare - it does appear that they usually raise stack with tap vs hold on runs that are more clearly RTA as well as TAS, so I'm not sure that particular point holds up. That said, the movement does appear to be smoother than standard play. One note is that in reviewing they have some runs listed as "touch control - non TAS" - these reflect a much different play feel than their other presumably controller based runs. I'm not sure if this difference would be enough to account for the unhuman looking "smoothness" of the run in question, but I think it bears review. My opinion based on a watch of all their posted runs and the above points, is that this run MORE closely resembles their previous "TAS" runs than it does their previous "RTA" runs, (based specifically on cursor movement speed, smoothness, style, consistency)
