i misspoke a bit, that 0.000003% chance for 5 beenests is actually chance of 5 beenests to generate in a row, the chance for that can break flying machine is bit higher, because there are 56 different ways to make choose 5 out of 8 trees, like 1 beenest grew on far left and other 4 grew one after the other on right or in many different ways and in similar manner 6 beenests or 7 or 8 can be calculated
there is a simple way to solve the issue, instead of using cross-section of flying machine and its extension to "mine" out the leaves, it can be done with wider extension but that will force me to use a different flying machine to rearrange the part of main flying machine sandwiched between extensions, this will bring same delay that i tried to avoid from previous design
