If you count the time between lag end and lag start, this movie only has it 1 frame faster because the IGT starts ticking 1 frame sooner. If you count from IGT start to lag start, the time is the same (1017 frames). If you count from fade out to lag, this movie is 1 frame longer. Since everything is fluctuating due to accuracy changes, I'd prefer to rely on something that doesn't fluctuate. I copypasted the new input starting with the first non-lag frame, and the IGT ends at the same frame as before, though lag starts 1 frame sooner with this input.
What I mean by loading times is that if you count from when the ship appears in the first level, to movie end, this run is 9 frames longer. I'm not saying this improvement is completely invalid. I'm saying a gameplay action only makes non-gameplay 1 frame shorter. If we have a consensus that this is a valid improvement, I'll accept it. If we look at our
glossary definition of gameplay, this improvement is on the edge, because it doesn't improve the in-game puzzle, but it kinda improves the overall TAS puzzle.
