apologies i've not read through all the recent posts - assuming i'd understand it

it seems to me that all the maps being completed can be done by humans just as fast
the problem maybe is just the generation of the maps
all the recent completed maps look like this:

the bots don't need to be that "good" (assuming they are bots) - they just need someway of finding easy paths by generating millions of maps - probably someone could just generate the maps the same way and then play it as a human (assuming this isn't what's happening now)
maybe if each map has some permenant blockage to prevent it being just a "freefall"
very crude image example - and would need to be thought about more

this way, any bots need to move / change directions - probably/maybe making it more complicated, so they can't just fall to the coin (they will still do it eventually) - and maybe the blockages would need to move slightly randomly based on blockhash (so doesn't change when F6), but atm i think they aren't as smart as people think (from looking at the replays).
wouldn't be a permanent solution mind you
note: I could be wrong and the bots have it down to perfection - and the generation of the maps in this way is just an extra bump for completing it quicker
