The old pros could out putt any of you with their bullseye putters yet today.
I think that's undoubtedly true and not germane. It's not about me. I'm not a high skill player and I don't use a high-tech putter. It's about challenging high skill players using the most advanced implements.
Pat Mucci pointed out, correctly I believe, that improvements in balls have also played a role in the increased % of makes of 4 and 5 footers.
I am curious to know whether, solely or in combination, changes in green shaping and maintenance methods might be used to lower the percentage of 4 and 5 foot putts made by high skill players using these advanced implements.
Perhaps coupling better sand distribution techniques with a ground mapping lidar accurate to a millimeter or so could create very difficult to read greens.
I think existing courses could have very difficult to read greens within a couple of years by using higher-tech maintenance tools.
Would existing mowers would be able to cope with many small, close together, opposing elevation changes?
