I feel like I could make a botted run that would be indistinguishable from a regular good player

Your argument seems based on the assumption that every botted run would be impossibly fast or make use of things not humanly possible, but it's very possible to just bot a run that doesn't do anything impossible and still beats the time.
Assuming the bot maker isn't an idiot you wouldn't ever be able to tell all it was a bot

If it is not impossibly fast, then a human should be able to beat it.
