Problem to understand Frame setting in Average Function

Good Morning,
I have a mechanical simulation and I need some help to understand the average frame setting.
I have Average1 (aveop1) with a Spatial Frame and Average2 (aveop2) with a Material Frame. Both Averages have the same point selected.
My results show me the following behaviour...
aveop1(z) = aveop2(z)
aveop1(Z) = aveop2(Z)
My conclusion is, that both frame settings are leading to the same end result. (at least in my simulation)
My question is: If there is no difference, why can I choose between this frames? Are they usecases in the average function in which they matter?
Thanks a lot.
Sören

The frame is irrelevant for point selections. The average of the value in a point is simply the value in the point. When you start computing averages over objects of higher dimensionality, it matters, since there is an integration being done.
