The relevance of the dominant eye in green reading

But more importantly, a ball rolling across a green, on a green with the exact same amount of break the entire length of the putt, doesn't curve in a parabola. It's not even close. If your method is based on the ball tracing a parabolic shape, it's inherently flawed.

Just out of curiosity, would the 2D projection be more like a logarithmic curve for a simple (not double or more) break?

Also, did anyone test out the original premise about favoring the above the break / hole vs. the below the break / hole premise? I have heard and experienced that they can disagree.

Not quite. Most of the simple ones are too sharp in the middle. It's just physics though. Gravity, time, friction.

But it's not a parabola. The time it takes the ball to travel the first ten feet of a 20-foot putt is not the same as the time it takes to travel the last ten feet.

Also, did anyone test out the original premise about favoring the above the break / hole vs. the below the break / hole premise? I have heard and experienced that they can disagree.

The answer is that you simply want to putt the ball on the proper line. People tend to under-read break (particularly if they aren't using AimPoint).
