Ok, move the SME arm forward you change the off-set angle yes.
Again, if you are running on the pin-point of the stylus, it has NO influence at all, at what angle that pin point rubs on smooth vinyl as a pin has no unequal sides --- unless that is only the case in my universe...
The change in friction force caused by a change in VTF of that pin-point is of course of MUCH greater influence and goes hand in hand higher VTF asking (all things being equal, which in the groove they are not...) for higher anti-skate compensation.
Also, the over-hang for a given arm is a ~ fixed parameter and as such it can actually be disregarded, fair enough.
There the variable is the VTF / friction force => stylus geometry.
As to the "off-set" it is the same as with the over-hang i.e. fixed also for any particular arm geometry and therefore also can be disregarded.
