Aimpoint Clinic: My Personal Odyssey to Putting Enlightenment (Part II — some Q & A)

Aimpoint Byron Nelson 2010

Part 2 of our weekly series on Aimpoint.

If you don’t mind I’d like to hear how you do in your first round using this.


I think it will take several rounds and several practice sessions to better understand the implementation. I am going to take the next 2 months and go out to my course in the evenings and study the greens. I will go so far as to make green charts, like yardage books, of each green. The explanation I gave refers to a straight planar green. when you have saddles and crowns it’s more complicated, and I don’t quite understand that yet.

It sounds interesting but i’m having a little difficulty grasping this zero line.


On a planar green, which is a flat tilted green… if you went around the hole and putted a 5 foot putt at each degree (so 360 degrees/putts), 2 of those putts would be 100% straight. That line is the zero line. Every break on every other putt is calculated off of that line.

In reality, for practical purposes, the actual zero line could span maybe 5 degrees, or the length of your foot. then you figure 30/60/90 degrees off of that zero line.


But how do you determine slope in degrees? For me I would think severe, not so severe, and non existent? Any way to pigeon hole these breaks?


They use %slope. flat= less than 1%, avg=2%, steep=3%, severe=4%. They say on tour, with greens running stimp >12, it’s never more than 2.5%… more than that the putt is too hard. Slopes more than 4% will rarely hold… they’ll roll down to a flatter surface. You might have to putt through a >4% slope.. they tell you how to handle that. But the charts they give you go up to 4%.

I bought a 9″ digital level that gives you %slope… so i’m going to calibrate my eyes to learn what these slopes look like.

  1. I haven’t checked in here for a while because I thought it was getting boring, but the last few posts are good quality so I guess I will add you back to my daily bloglist. You deserve it my friend 🙂
