I have zero problem with someone who uses spreadsheets or rulers or visual aides in order to help calculate their shots. Pro golfers and caddies do basically the same thing in their yardage books and preparation. I, for one, don't go nearly that far. I made a single sheet club mapping a couple of months ago, which helped a great deal, and I ended up memorizing it, so I no longer need it. I also play exclusively mobile, and I don't really have a way or place to keep that stuff handy.
The way I see it, people who live and die by that level of specificity tend to just get more frustrated when their shots aren't dead perfect, so I feel like I get more joy out of the game by simply doing the math in my head and executing to the best of my ability.
Where I have a problem is with the ability to buy a better shot. I'm not talking about buying clubs or balls that go longer, fly a little straighter, or spin a little faster. Those are all part of real life golf. I have a problem with the ability to buy a slower swing meter through equipment, balls, or any other means. To me, that's like being able to buy an instantly better swing on the real golf course. While a real golfer can buy lessons, they still have to put in the work and practice in order to get better. They don't just pay money and step out on the course with a better swing. I believe that the swing mechanics should remain the same for all players, regardless of skill level.
