>which is actually faster than the 20:44 TAS!

I had no idea what this was.

For people like me, after clicking through the link and some googling:

TAS = "Tool-assisted speedrun" or "tool-assisted superplay", and they are "generally created with the goal of creating theoretically perfect playthroughs".

That any% run was fun to skim through though. I had no idea what was happening.
