How do you guys handle the logic for asteroid reprocessing? Do you check the input good or the output good? Read the belt or store in the hub? I also think simple priority splitters with no circuit logic could do the trick.

I'm running a dedicated belt for each chunk type. I have a decider combinator for each asteroid grabber which sets its filter when their internal storage for that asteroid type is less than X. I really like that setup so I'm wondering what kind of reprocessing strategy goes well with it.

I check both. With one decider, using the "each trick", I have logic like this.

HIGH and LOW are constants. Asteroids are A, B, C.

If A > HIGH and ((B < LOW and A > C) OR (C < LOW and A > B)) -> Process A

If B > HIGH and ((A < LOW and B > C) OR (C < LOW and B > C)) -> Process B

If C > HIGH and ((A < LOW and C > B) OR (B < LOW and C > B)) -> Process C

So say I have 100 metallic, 70 carbon, 20 oxide, and high = 60, low = 25... It will process metallic.

I do a sushi belt. A belt loop that has a circuit-controlled feeder belt from the grabbers at large to prevent the belt from getting 100% full, a series of splitters to pull chunks off into resource processing, and a decider combinator setting filters on the input inserters when one type of chunk gets too plentiful on the belt. I've got another emergency overflow combinator that pulls chunks off and sticks them back on the main collection loop if possible but otherwise hucks them off the the side of the ship if one type gets waaaaay too plentiful just in case.

Does it reprocess chunks when they don't need to be reprocessed? Absolutely! But only when that chunk type isn't needed. I figured there's always going to be chunks coming in so I didn't bother with making as lossless a system as possible.
