With the forward and reverse views, a fairly good representation of the green can usually be inferred. However, sometimes, the data appear to conflict between forward and reverse views. It doesn't happen often, but it does happen.
There are a few things you can do to make reading such greens more accurate.
- Switch to "Pitch" or "Chip," if you're on the fringe, and you'll see a different grid formation. Sometimes, this alternate view provides some enlightenment. (Now that I think about it, I don't know if I've tried this from anywhere but the fringe. Maybe it will give you and alternate view from the green too. I'll check)
- Move the aiming arrow around a larger area of the green. Sometimes we get lost in the minutiae of putting and forget to see the big picture. Greens have a fluid shape and a certain logic to them. Sometimes, moving the target around exposes features of the green you have overlooked, features that might affect your decision on a right or left breaking putt (Though if it's that unclear, your usual shot is to either lag or hit it hard and take the half-assed break out of the equation).
- A hybrid of the first two points, and for the same reasons, is to switch the swing to "full" and take a bird's eye view of the green.
In the end, I see it as part of the game. The information is almost always there if you know how to look for it (Do you play for wind on putts? Most people don't). The challenge of golf, both in real life and in this game, is really less about execution and more about interpreting the situation.
Use those tips. They help.
