David,
If you take a look at the composite course I listed in the original post, what you'd see is a course that had only 5 eagle (all on Pebble Beach 18th)and 639 birdies in 4,267 attempts. Meaning that PGA tour players recorded an under par score only 15% of the time.
This isn't a question of what may happen. The best players in the world have played all of these holes in 2020 and did not destroy them.
Lets compare the holes on my composite routing to the best in scoring efficiency on holes of these distances across the PGA tour:
Par 3's (161, 162, 179, 188)
(2) PAR 3 EFFICIENCY 150-175 YARDS - Adam Scott - 2.783
(2) PAR 3 EFFICIENCY 175-200 YARDS - Tyrrell Hatton - 2.767
Par 4's (349, 351, 365, 370, 380, 381, 381, 389, 395, 398, 418, 438)
(1) PAR 4 EFFICIENCY 300-350 YARDS - Tommy Fleetwood - 3.222
(9) PAR 4 EFFICIENCY 350-400 YARDS - Webb Simpson - 3.733
(2)PAR 4 EFFICIENCY 400-450 YARDS - Scottie Scheffler - 3.896
Par 5's (543, 570)
(1) PAR 5 EFFICIENCY 500-550 YARDS - Webb Simpson - 4.227
(1) PAR 5 EFFICIENCY 550-600 YARDS - Tony Finau - 4.402
Total: 64.34
So the best of the best in each category would average just shy of -6, keeping in mind that this is all holes not just the most difficult, which my routing represents.
It's reasonable to believe that on this routing the low round of each day would hover around the 64-65 mark, with the daily average being around 72-73.
Propose to Lou Stagner my routing and have him calculate what he thinks the winning score and tour average would be.
