Hi,

Since you're adding an additional tier of belt stacking, it would also be a good idea to get an extra +4 to hand size research to go along with it. Since stacking to 5 means you'll be dropping 3 stacks of 5 for a total of 15, compared to vanilla where you'd be dropping 4 stacks of 4 for a total of 16 items, which actually means you're losing out on 1 item per swing by having the extra stack size. This -probably- still comes out net positive on belts, considering the swing time for 3 stacks vs 4, though I'm not sure how that works for chest to chest. But in any case, with an extra +4 to hand size, you would hit the next threshold of 20, so you'd now drop 4 stacks of 5 for a total of 20 items. A nice even number :)

That bonus is only there so if you'd unlock it before the normal stack inserter then it actually does something.
I'll also have a different stacking tech for the rework, so I'd rather not touch it for now.

I also have no intention of shutting you down, I just walked through rewriting 4 internal modules and at least 2 are still left.

It's no problem :)
