I was messing around with level 10 and I discovered that it could be beaten with only 3 boxmen. I haven’t had the opportunity to record it, but when I do I will show you. Not only does this mean minimum boxmen will change but it could also be a (slightly) faster strategy in Any%.

I already know that 3 boxmen is possible in both 10 and 11. The strat for 10 is the EXACT same as the normal strat with the slight difference of placing one boxman in the ~middle of the hole instead of two boxmen to the left and right. 11 is the only level with a unique strat for min boxmen.
