Chines gold seller confirmed, ban please!
Seriously, I got a woodworking set close to 500 total and I get 80-95% out of 40-50 boards samples, whereas I'd say the average is around 90%, that might sound high, but it still means you lose 5 out of 50 boards, and as oiling has only a 50% chance, you need to apply that recursively there getting you a total loss of nigh 20% which is 10 out of 50 boards which is something I consider quite a lot for having a decent woodworking set already.
pretty sure that 20% number does not accurately portray the 50% chance on the oiled boards... if 10% of boards fail on the first planing out of 100 and you oil 90 board afterwards of those 90 45 must be oiled again. which means you would have a loss of 4.5 boards meaning that of the 100 boards you lost 14.5 which is a 14.5% on the optimal.... Now taking in the 50% probability (Cant remember if this is the right formula but I believe it is) .10 + .50 - .145 = .455 on worst case you keep 54.5 on best case .10 + .50 + .145 = .745 you keep 74.5% of your boards.
That is not correct, taking 10% it goes like that:
10 loss, 90 planed, => 45 oiled, 45 re-plane
4.5 loss, 40.5 planed, => 20.25 oiled, 20.25 re-plane
2.025 loss....
you see, it adds (slightly less) than half of the loss of the previous iteration, now if you know math then you see how this is similar to 2 by power of...,
whereas 2^x is exactly one more than all previous ones together, like 2^4 = 16, 2^3+2^2+2^1+2^0 = 15
Though here it s not even 1/2 but slightly less (1/2 of 90%) so you see if you start at 10% it gets close to 20% but just close.
