I knew that TAS meant “a computer” but for those, like me, who forgot/ didn’t know, TAS stands for “tool-assisted speedrun”.

[jmcgough]

Correct. TAS usually means to use a tool that lets them painstakingly play the game on a frame-by-frame basis (usually 1/60th of a second), each frame making the theoretically optimal input.

Yes, and even for TAS you usually have a division of labour between people who find the exploits and people who create the TAS itself.
