The OP can google it for more information. I have done so and even looked for a class close by. For those of you that use it, how much time does it take to calculate and be confident. I am thinking that you can probably do it in the same amount of time that you would normally use. Good point about the "knowing for sure" as lack of confidence, can ruin the best read putt.
It doesn't take long at all. It takes a lot of practice to get good at using it, but on the course while playing, it takes as long as it takes to ... pace off your putt to the hole, stop for a few seconds halfway back, walk behind the putt to pick your aimpoint (while walking back there, your getting the number from the chart), step up and hit it.
And because I can frequently pace off the putt ahead of time, if I'm not the first to putt, I can skip that part. If you were previously the type of putter who reads a putt from behind the ball, and behind the hole, and the side, aimpoint would actually be faster. If you were the type to just read from directly behind the ball, it might be a tad slower, but it's still really quick.
Erik did a demo at our class and I want to say it was something like 20 seconds from the time he marked his ball to the time he hit it, after going through the whole process.
