Initial rate solve (750G):

found the left part which process one of the rust input pretty soon as the puzzle release, with water from another rust this produce 5 out of the 6 salt-product with very few arms per 20 cycle

then the hard part comes in, the sub-4 rate means that period-4 pipeline is not sufficient

after a lot of attempts, the right part end up with the period-6 pattern generating all 6 quicksilver-product in 3 period (and 2 cycle stalling) with 2 pipeline sharing the metal-quicksilver bonder so the logistic become easier

remaining atoms could be send back to assemble the remaining salt-product required

spend too much fixing things, might make some improvement later

Update (-15G):
fixed the piston

Update 2 (-25G):
clean the bottom right mess a little bit, have to program that track loop that occasionally stalls
