It seems to me the math isn't great with inserter timescale selection. I understand there is some room for error in regards to arm movement, resource input, and resource output; however, it doesn't seem even close in the math.

Example: Red belt produciton in assembler machine 3

Gear input reads using only 0.339% of a single fast inserter; however, the machine has a ~1 sec pause waiting for gears from a single fast inserter for each production run. This is a base, unboosted assembler being fed from a full blue belt of gears using a single fast inserter.

Is there something I am not understanding or is the math that off?

I also added a comparison with the older mod, Max Rate Calculator, which shows needing 1.353 fast inserters for gear loading.

Okay, I have done additional testing with all other mods removed to confirm it isn't something else causing this problem. I assume through process of elimination that this mod's fomula for inserter requirement is very inaccurate. I don't know how anybody else has mentioned this before. It seems to be off by ~4 times what it should be just from my basic knowledge of numbers.

New test:

Assembling maching 3 running express underground belt production.
Requires 50 gears a second.
Bulk inserter is capable of moving ~15 items per second.
50/15=3.3 bulk inserters required (Roughly)
Rate Calculator+ is showing 0.15 bulk inserters required per machine. That is 4.55% of the required ~3.3.

Or am I just a dumb and reading this thing incorrectly?

Thanks and hopefully this issue can be resolved soon as I much enjoy this kind of mod.
