T,
Am a retired GD rater. Left about 3 years ago.
When was rating, garnered as much info before playing a course so that nuances during the round could be better absorbed.
Played tips, but always looked at the other tee positions, lengths, angles and visuals. Imagined play from those tees by my father (the definitive 16) and Laura (who was as low as a 6 and had the game/length of a male senior) and my mother (the definitive lady golfer).
Looked at the varying fwy landing zones for each tee and the respective lie, distance and approach requirements.
Noted bunker positioning and depths, especially on how they affected recoveries.
Payed very close attention to green complexes and would spend some extra time at interesting green portions or recovery positions.
NEVER kept score.
Often played alone. And early, so that any 'loitering' would not bother others. NEVER with a foresome of friends. Sometimes with Laura. Rarely with anyone from the host club.
Made many notes and took many pics.
Wrote out a review that was sent along to the mag, explaining my scores.
IMO, the GD scoring is too perfunctory. BEGGED them to add 'Enjoyment/Fun' as a category. Got nowhere.
Had to retire due to some physical issues. Have since rebounded, but am staying on the sidelines.
