It will wear the joint out doing this. Closer to straight is better. Actually straight is best. Use a tubing bender mag base angle finder. Put it on the top of your drive shaft and then on top of the pinion guard. The two should have the same deflection off "0" or be at the same angle from 90 degrees.

just to add to this...perfectly straight is sitting still/not moving...the reason for 1-2* under straight line is for driving or acceleration...the pinion will rotate up-there by-being in a straight line while under powermokin:
