2^800000000 floors long I think let me check at lunch this uses nested lists for the mechanism and is bigger than 2^10600000 which is normal list limit
note: this is based off of a frictionless called AN ENDING. its length is pretty much a AN ENDING but scaled to 100000000 independent variables so uhh the average time is around ~2^800000003 to ~2^800000010 if nonstop has no kill bricks omg
