£200? Insane. Does you get a free magnetic bracelet with the course too? Or an energy drink?
Not sure where that figure comes from (and in work so can't go looking, but I only paid £90 and as said already have the option to attend another course free of charge as a refresher should choose to do so
Have you had time to consider a response to Imurg questions ?
Very valid points and question I believe
I agreed with him regarding the point about needing to start it on line although that applies to whatever method you adopt. As for double breakers, the easies thing to do is take two measurements for each slope to see how much it moves. BEFORE anyone says it takes too long, I can do an accurate read inside 10-15 seconds which I'd argue is as quick as someone studying their putt in a traditional method although TBH that is a side issue and not the point in question. A downhill/uphill putt works the same way as you're measuring the angle of the slope so take the mid point for both parts and get a read. There is a more advanced course that the pros and caddies (and open to the public if you really want it) that gives the absolute definitive way to read these sort of putts but at my level, splitting it into sections works as well and I can still get an accurate read.
As I've said, those that use it think its great and reliable. Those that don't have their own preferred method. Each to their own and as a game about getting a white ball in a hole, how that's achieved is immaterial as long as it's done as quickly as possible
