It's alright anon, I had to fiddle with it myself too.
Splitting things between just two channels is a pain as well. I'd love having an extra wire color/channel to keep things neat and separate. RGB ftw.
As for the physical layout:
>C0 - hub content filter, every value at 1 (optional)
>C1 - constant for chunk limit, all values at 1, group multiplier is 10
>C2 - constant for processing product limit, all values at 1, group multiplier is 100
>D1-3 - deciders with the same layout of "if G:product:threshold < R:product:hub AND G:chunk:threshold < R:chunk:crusher loop then reprocessing recipe"
>A0 - hub content filter R:Each * G:Each (optional)
>A1, A2 - arithmetic combinators with R:Each - G:Each
'Roid collectors' filters is set by wire, crushers' recipe is likewise set by wire.
Wires dangling about for clarity, usually I just chain-wire things, like with the crushers.
I hope this will clear your confusion. Please feel free to reverse-engineer it to your heart's content, it's how I learned things too.

The biggest selling point here is the fact that you can scale this thing to any number of crushers.
Adding new chunk and product types to limit is easy too.
