At age 64 I’m playing my best golf over the past 3 years and averaging 90 rounds a year. Set new PRs: average score below 83 (83.2 is best year), keep index below 9 (ranged from 6.5 to 10.6 last year), break 80 over 20 times (17 is best year), shoot par golf for a round (had a 73 last year), achieve 90% “safe” drives (can advance ball at least 100 yards on 2nd shot), 50% GIR, 83% GIR+1 (having a putt for par).
