I may be wrong, dry, but as I undestand it using the chipping view allows you to see the true break of each square. The break of each square is measured in the middle of the square, not either side, so using the chipping view allows you to move the aimer around to see the middle. If I have questions when seeing differing breaks along the grid lines I'll revert to the chipping view to sort it out. Works for me that way, anyway.
As for the reverse or front view, I never stroke a putt from the normal view. I always line up my putt from the reverse, then stroke it from the same.
Happy golfing to you, dry. Good luck.
