I do agree because most people think they are a certain type of putter and then when they see the stroke on SAM they are amazed. The biggest thing is knowledge, 90% of golfers have no idea that they can get fit for a putter, or have any idea that the loft and lie of their putter is just as or more important than their irons.
What would you say is the most important club in your bag? You use the putter for about 43% of your strokes (give or take). I see you posted some pics from SAM Putt Lab and that is one of the best monitors to use for putter fittings. The club most amateurs get fit for is driver, and you only hit it 13-14 times per round. The money you will spend on a putter fitting will be the best money you have every spent!
