Everything I have read however regarding the driver says that the Arc of Approach should be positive, that being, hitting on the up stroke to minimize spin and therefore increase distance.

Indeed, the data provided by Launch monitors and club manufacturers is to take into account.
However, the concept of hitting up with the driver is misleading the average golfer who understands it as an encouragement to scoop under the ball with the driver in an attempt to lift the ball in the air...
But if you know your lessons and mix to your advantage:
ball position relative to low point,
the aiming point concept,
the launch monitor's data,
you should end up with the ball positioned an inch up plane after low point and touch the ball on your clubhead's up travel.
Now, it is vital that you must not forget to direct your thrust DOWN even AFTER LOW POINT.
Low point is not the end of the DOWN because you should still have some right arm to extend untill the end of the follow through (both arms straight).
This is the only way to stay TGM correct (geometrically correct) and use the launch monitor's data to your advantage.
