My understanding that there is no "mathematical formula" for the "expected DIFF" for a given index, just a collection of tabular data that USGA/R&A use. I just reverse engineered that table from the OKRASA web site. I do not know the veracity of that site, but it seems pretty trustworthy. As...
Hi Y'all - Thanks for the chat above.
I made this table of "expected scores" just by using that cool OKRASA link above (http://golf.okrasa.eu/language/en/handicap-en/whs-en/score-differential/#Calc).
Odd that it is not published, since it is easily extracted like below. I guess my initial gut...
Followup question please on the new 2024 WHS rule for generating an 18 hole DIFF after playing only 9 holes. Easiest to ask by way of an example:
1) I have an index = 14
2) I play a 9-hole round and shoot 44 (adjusted) on a course with the 9-hole data: CR=35.5, CS=138, PCC=0.
3) The 9-hole...
