I think I strained a muscle in my chest at some point between practicing on Thursday and playing on Friday, so I'm not up for full swings today. Instead, I took my driver and rehearsed the swing from A6 to A8, concentrating on making an upward strike through impact. I think I can get a few more yards off the tee if I can hit up more consistently.
According to Broadie, what is the expected dispersion width for the average 90-shooter? How does that compare to the accuracy chart for a bogey golfer in the course rating guideline? The USGA bogey golfer model does not reflect reality as accurately as its model for the scratch golfer. I notice that you keep avoiding addressing that specifically, but AFAIC, it's really that simple.
I'm aware how it would affect HCPs. I'm for accuracy & portability.
IMO a statistical excess of players playing better than their course HCP on non-home courses tends to enhance a mis-perception of 'all those sandbaggers' out there. Perhaps with increased accuracy in course comparisons there would be less 'need' for the 'bonus for excellence'?
