You have a carpenter's best production answer and a good scientific
formula to determine the tolerance required.

But if you are worried about the hinge pin location or the swing of the
doors in relation to the pin location, Maybe you should find a scrap of
ply-wood or a piece of 1x6. Draw the doors as you would want them to
look and when you have the spacing that is acceptable, Use tramel
points or a home-made compass to mark the swing of the panels. One
point in the middle of the hinge pin location and the other at the
furthest corner from the hinge where the doors meet. Then mark the
other swing for the other door. If the radius marks cross then that is
the amount you need to remove.
