Yes yes, before I get verbally abused (joking) over splitters not splitting properly, take into mind that I'm looking for logical advice as to why things are happen, rather than even more proof that that they are happening to begin with.

If you have a 270 belt and you split it into a 270 and a 60, you'll get neat little sections of 4 items in a row, and then a gap, without fail.

If you do 450 into a 450 and a 120 you'll get neat sections of 3.

If you do 270 into a 270 and a 120, you'll get neat sections of 2.

This is probably because 270/60 is 4.5, 450/120 is 3.75, and 270/120 is 2.25.

And yet, if you do 450 into 450 and 60, you'll get some sections of 6, and some of 7 with no discernible pattern between. 450/60 is 7.5.

Ultimately belts are transporting discrete items. Items don't round up or down, they can have distance from each other and follow rules; I can't fathom where those sections of 6 are coming from, so I'd be happy to see if anybody else has any ideas on the subject. Any idea is accepted. I'm sure that there's just some point of view that I haven't looked at it from yet.
