I'm looking into speedrunning this game and there's one thing I'm unsure of. Is the run finished after completing the first 10 worlds, or do you have to unlock and beat the last two secret world as well?

I ask because you have to farm 2006 bananas after beating 11 worlds to unlock the last one and I don't know if it's possible for even the world record holders to have done so that fast. Maybe you have to have all the worlds unlocked from the start and just beat each one? Please help.
