2019 to today (5+ years) I have done stats on paper/excel.
Spring 2023 to today (14 months) I have done Arccos.
So far it has been a good learning tool to compare my current stats (6.5 index) to my best stats (5 index). Arccos breaks down your round into 4 folders (driving/approach/short game/putting) with subfolders from different yardages/distances.
I am not a big fan of practice, but with the data I can ask an instructor what areas to focus on that may make the biggest differences.
Truthfully when I was playing my best in 2023 I was playing frequently with 7-10 days maximum between rounds (all year round) and focusing on maximizing my GIR.
