Hi,
I have created a roller and mass flow conveyor with the same parameters. The mass flow conveyor is having a width rule with the number of lanes 1.
The conveyors are having the same speed, length, and flow item size. Initially, for some period of time, the throughput remains the same. And after some time there is a difference in the throughput. I believe it should be the same since the mass flow is using a width rule here.
Attaching the model for reference.

As far as I can tell, this is the designed behavior. See this answer for an in-depth explanation:

Yes - it looks like the regular conveyor has extra gaps between the items.
Change your decimal displayed precision to 6 digits and run this script with items on the conveyors:
- applicationcommand("outputconsole");
- Conveyor conv=Model.find("StraightConveyor1");
- Array convItems=conv.itemData.toArray();
- double lastpos=0;
- double pos;
- for (int n=convItems.length;n>0;n--){
- pos=convItems[n].as(Conveyor.Item).position.x;
- print(n, " Pitch is: ", pos-lastpos);
- lastpos=pos;
- }
You'll see the items on the regular conveyor are sometimes 0.2mm apart where there should be no gap. You can even see the gap visually compared to the mass flow conveyor.
I'll send it into the developers for them to consider.
