im having trouble seeing how adding an inch (25mm) to the front is only going to effect the mounting position by 12mm...

its simple since ur making the wheel a inch wider the new center of the wheel has changed which effects the offset. Since you now have changed it by 25mm u need to divide it in half so u get 12.5mm and subtract it from the offset. This is why when u get a 25mm spacer ur only adding the 25mm because the wheel center didnt change just the hub of the rim. its like adding 25mm to the front and taking it from the back barrel pushing it out 25mm.
So in the end no matter what you will still have the wheel stick out 25mm more using either method but offsets willl be different.
Simple as this dont think of being more flush because u have low offest wheels because similar size wheels with same offset can have different fitment because we need to consider what the backspace is and the hub of the wheel where it attaches to the cars hub
ahhh it fucking sucks trying to explain this to someone not in front of you
