From the tool tip on each belt I got these numbers and then divided by the yellow belt items per second.

Belt Speeds
Yellow 13.33 1x
Red 26.67 2x
Blue 40.00 3x
Green 53.33 3.265x
Purple 66.67 5x

Thank you for the great mod. It has saved me a lot of belt and UPS.

Bob's Mods also has faster belts. Is that part of the plan to add those level of stackers?

I was wanting to know if you are going to add support for Bob Mods?

I am getting a dupe bug when I am trying to split the items. It will split the item but also output to the belt stacked items as well.
