I have one lesson remaining from a block of 4, so if the putting green in open I'll get it on putting. Maybe I need my putter adjusted, i'll ask the pro for his opinion on Saturday.
What I've started trying to do before I play is to go on the practice green and hit half a dozen balls each with 3 different length (roughly repeatable) strokes. One about 12", one at 18", and one of 24" (short, medium and long).
Measure the average of each one then you have 3 different differences you can 'roughly' hit on the greens.
I'm not a particularly good putter but using this method I've stopped going 6' past or 6' short on the longer putts.
