So, this is just like the title says. I spoke too soon in the thread where I said my tests showed that the mod behaved as I hoped it would. Since then, after playing with it under actual gameplay conditions, I've found out that pickup offset doesn't actually even DO anything.
Picture this:
A belt, completely backed up on both lanes, with the same item in both lanes. Not moving, except when an inserter pulls something off so that that lane moves a little from behind the inserter's position to fill the vacancy.
A row of inserters on one side is pulling stuff for their machines. They of course pull from the near side, since this is their default. They only pull from the far side if the near side doesn't have what they want, and the far side does. Both lanes have the same stuff in this scenario though. So they always pull from the near side.
I want both lanes to keep moving, so I set the pickup offset of every-other inserter to pull from the far lane.
Nothing changes. They ALL still pull from the near lane, and ONLY the near lane, even though the far lane has what they want. Pickup offset doesn't even work.
