Everyday round ratings should factor in weather conditions, especially wind. Shooting the same score in calm conditions versus 20+ mph wind are completely different rounds, and the rating algorithm should reflect that. Even a simple wind adjustment using local weather data at the course and tee time would make ratings feel way more accurate and fair.
Also, course difficulty should probably be weighted more heavily too. Right now, some extremely difficult championship-level courses feel underrated. Shooting a +12 at a course like Nockamixon is a way stronger round than the same score at an average local course, but the ratings don’t always seem to reflect that accurately. Factoring in course difficulty, scoring spread, elevation, OB density, and punishment level could make ratings feel a lot fairer and more representative of how hard a round actually was.
