Regardless of where it’s “supposed to be”, the fact is...... you line up the dots, take your reading and it is where it is.
If that isn’t where you want it...... you move it........ however much it takes to put it where you want it.
The motor doesn’t know or care about where the dots on the timing set are.
It only reacts to where the lobes are phased in relationship to the crank(which is often not the same as what the dots would indicate).
If you have a cam with an LSA of 110*, and it’s in the motor with the timing set at “+8*”, but the degree wheel says the cam is in at 112*........ the cam isn’t advanced........ as far as the motor is concerned, it’s retarded 2*.
