Keve - you haven’t told us your COURSE handicap - this will show how many shots you received for the nett double bogey hole - this may be different from your Playing handicap.The stroke indexes and pars will also be needed

What about par and SI of 18 ?

Nick - I have a question for you as our WHS Guru:How is the individual round Score Differential actually calculated, as despite having a university degree in engineering I'll be buggered if I can work it out...So yesterday I shot a 73, I have a WHS Index of 4.1, I played at Tidworth Garrison GC, white tees ( Course rating 71.5 / Slope 130) giving me a course handicap of 5. According the the EGU MyGolf app this gives me a Score differential of 1.3 (PCC was zero, as it has been since they introduced the WHS at our place).How do you calculate the 1.3??Other random scores are with SD after the / and HCap in brackets - all on the same course / tees and zero PCC:77 / 4.8 (4.6)87 / 13.5 (4.4)81 / 8.3 (4.1)74 / 2.2 (4.7)73 / 1.3 (6.0) - this is the one I don't understand - how can this score when played off a higher WHS Index and course handicap give the same score differential as the 73 I posted yesterday?

Ok....so first of all....your existing/current WHS index or course handicap plays no part whatsoever in the calculation of your score differential.The score differential is purely a function of your score, compared with Course Rating and then normalised to a course with a Slope rating of 113.Score Differential =(113/slope rating)*(adjusted gross score - course rating - pcc)So in your case Score Differential = (113/130)*(73-71.5-0)which you will find is your 1.3

I just accept now that the differential is what it is but last weeks at the Downfield open made me scratch my head.I had a shocker of a round, scoring 2 7's an 8 and a 9 for 88, gross adjusted to 85 on a par 73 course. In my, and everyone else's defense, the course had been set up the day before for some international boy/girls event with flags perched on ridges and the greens running like putting on car bonnets.I woke up at 3.30am for my usual pee and was stunned to see the differential was 8.1 and I had been cut by 0.6. The winning score in Div 1 was 74, 1 over net so very tough.Sent from my SM-S906B using Tapatalk
