You can always mark down max slope numbers, and which way they break as well.
Did you do MidPoint or Express? Just curious.
For three or four spots on each green, write down:
Then you can always use them to determine nearby spots.
A good example where AimPoint helped a lot. The greens at my league course were aerated a few days back. They did a great job of filling the holes, so the aeration did not affect putts. But visually it really created an optical illusion about the break. It was like looking at the green in a video game like TW golf. The dots appeared to make the break look completely opposite of what it really was. I had time, so I check the break a couple of times with my eyes closed just to make sure.
Aimpoint is so awesome.
Last night I played a round and had a putt of around 7 feet or so that had a lot of break that before the class there's no way I would have made but I stepped up to it last night and drained it. Felt awesome!
I also had a putt last night that looked like it broke the other way but I using Aimpoint, I trusted my read and left it on the edge of the hole for a tap in. Would have been great to make it but I know had I just trusted by eyes, I wouldn't have left myself a tap in.
