Flow rate compensation factor. What is it?

There is a couple of settings in the Experimental section in Cura 3.6.0. "Flow rate compensation factor" & "Flow rate compensation max extrusion offset". What do these two things affect? 

 

I couldn't find any documentation or explanation for these two settings. The tooltips in Cura for these two are a bit cryptic.

    Some materials are a bit strange when you extrude them. If you ask for 100 (whatever the unit is, doesn't matter), some materials only extrude 96 (or something like that).

    This is mostly an issue for machines that have flow measurement (Such as the S5). There are basicly 2 things that you can do to fix this. If you don't have a flow sensor, you "simply" pre compensate for this factor. So instead of asking for a 100 if you want 100, you ask for 105 in order to get a 100. The problem with that is that if you have a flow sensor, it will give a warning (Because you asked for 105 and got 100, which should be seen as underextrusion).


    Those two settings are meant to be used to solve this problem.

    so these settings doesn't have effect on "flow rate" at all, these are indications for the flow sensor to compensate, how to interpret what actually happens? Because it's set to 90% by default and I really like to have control over settings, but here, I'm puzzled. Your description is good, but "you "simply" pre compensate for this factor" is not clear.
