Arccos can help you if you enjoy getting into the nitty gritty of your game to really see where your misses are (short, left, right, long...) with each club. It also will make club suggestions based on what it knows about how you hit each club, which is nice. They know that not every swing is the same and have an algorithm to figure out what your best chances are.
I have yet to play a round where I use every single suggestion they make, but I really should do that and maybe it would help some?
My issue right now is my short game (not putting) is in the crapper, so Arccos cannot help that.
There is good and bad about it. I like being able to go back and see what I did during rounds, but it's not perfect either and every round requires a little bit of tweaking to ensure you have correct info.
