World Handicap System Now Out (2020)


Recommended Posts

After reading this, I actually have a thought....

What if only a few people with handicaps play the course on any given day.   I'm believing that the averages scores will affect the PCC adjustment, no?    Worse case, only one player with a handicap plays the course, does his score get adjusted, even if he plays in Caddyshack rain and thunder?

If one goes to the USGA site and looks at what is offered on the worldwide handicap system, due to debut in less than a year, the information is a bit vague.  This leads me to believe there continues

To this point, the world has had a few different handicapping systems. Among the major ones, we had the USGA handicapping systems, with course ratings, slope, the 0.96 multiplier, best 10-of-20

In following up on @iacas' post in another thread, I took a peek at the Golf Genius website.  The first thing I saw was a link to this: WHS White Paper.pdf - Google Drive

Thanks for the response. Do you know what the algorithm is? 

It’s not being made public.

Minimum of eight scores. And they’d have to be pretty far off of normal to warrant an adjustment.

This is the only problem I have with the new system. I will no longer be able to self calculate, as far as I can tell.

I don't believe from what I've read that it will make that significant of a difference.

Good to know. I am not that worried about it being perfect, but just a very good estimation. I guess when people ask me I'll just say I'm an (x) in 2019 format, I suppose.

True. But you can look it up the next day.

No. I could know the formula and I wouldn’t share it.

The other interesting thing is the stroke allocation for determining where you get your strokes for net double bogey will come from the last rating done at the course, so the stroke allocations on scorecards are no longer accurate for the handicap system.  They did say that the new app will allow hole by hole entry that will show the correct strokes.  Interesting thing in the CGA documentation that multiple PCC adjustments will indicate that a course may need to be re-rated.  I have found a big inconstancy in course ratings in my opinion.

That’s a lazy course.  Scorecards should be updated as soon as a course is re-rated.  I understand there is a cost involved, but it can be planned for, and not doing so is irresponsible.

Oh Bon... where in the world is your attention span.  We used to wait 15 days to see our new handicap... now 1 day is too long?  ☺️ [Please note smiley face]

For our members, I'm trying to find a document that describes how each player's scoring record will be processed to produce their first WHS revision on January 1st. Corresponded with the USGA who said there isn't one. 

Here's what I've pieced together about what our members will see different on WHS day one:

1. Index will be the average of the best 8 of 20 differentials instead of the best 10 times 0.96. (Or if they have less than 20 scores, see the WHS rules.)

2. If the player's index was at the maximum index it will likely increase, sometimes significantly. The new maximum is 54.0. 

3. They will receive the new "Low Handicap Index" - their lowest index during the previous 365 day period. 

4. Their tournament scoring record will be dropped and past scores will no longer be designated as tournament ("T"). Best two tournament scores will not be part of the revision. 

5. If their handicap Index was, as of the transition to WHS, Reduced (shown by an "R") by exceptional tournament scores, their index will likely increase because the reduction will no longer be applied.

look at the link in post #226.   @DaveP043 provided the links which help explain some of the changes in detail.

Yes, thanks. That is information I'm aware of.

I'm trying to put together a specific list of what our members will see different in the January 1st handicap revision. Everything that I have found is about how the WHS will work going forward, nothing about the specifics of the conversion from the current system. 

There is room for confusion. For example, one post on another forum said that old scores will be processed for Exception Score Reduction (ESR). The reply from the USGA said that is not the case.

Although there will be differences in the calculations, with the addition of the PCC, the changes to exceptional score influences, daily revisions, to me the single biggest change for most people in the US will be the introduction of net double bogey as the maximum hole score.  If you can get your members to understand that, I believe you'll have done the most important thing you can do.

FYI. This is slightly incorrect. Point #3 should read:

3. Anyone with 20 scores will receive their first Low Handicap Index, which will be the same as their first WHS Index. 

Also, regarding point #4, there will be "C" (competition) scores. Status as a C score will not affect index calculation, but is available for committee reference. Unclear whether "T" scores will become "C" scores.

Unlike the previous Handicap Manual, there is no specific guidance given for what could be defined as a Competition Score.  Left up to me, I'd broaden the definition a bit beyond what are currently defined as T Scores.  While the new Rules suggest that the different score types will be defined by the Authorized Association, it would make sense if they were further clarified by each Club's Handicap Committee.  After all, those type designations are there to help the Handicap Committee.

Where is your club located?  Are you the Handicap Chairman?

As handicap chairman for our Michigan club, I have the luxury of an inactive season; most of our members are not posting scores until April.  They seem to be okay with my statement that for virtually all of them, the handicap changes will have little affect on their index. You have an unusual group of golfers with the concern over all the details.

I'm in western Washington. Our active season begins again on March 1st, but members play all year. 

Would like to give them a heads up about what will be different in the new handicap revision they receive on January 1. You are probably right that most won't care though.

    • Day 158.  This morning I hit a dozen full shots (usual routine and place) with my 6-iron.   This afternoon, I began work on quarantine day 12 (trail arm throwing) -- without actually throwing the club.  Still, I can feel how this is different, and I'm going to go back and forth with this and full swing for a bit.
    • Day 36 (01 Aug 21) - More work on swing tempo focusing on getting a consistent 3:1 tempo.  
    • The above is the first I've heard of booster shots.  Hopefully I find a place to get one that doesn't involve over a half hour's drive to a city named Corona like my first two shots.
    • and, quoting the above: The line of best fit for the data of GIR vs score is 95 - 2 * GIR.  That's probably where @reidsou's number came from.   Note that, even if we treat it as the standard goal (I agree with you, as you'll see in a moment), an average 11-GIR round probably has one or two birdies thrown in, and I'd bet that most of those missed greens in such a round (again, for an average 11-GIR round) are probably very much near-GIR.  That having been said, there are some of us, such as the original poster on this thread and I, whose long game is such that more than seven GIR isn't unheard of (which that formula would "predict," if we use it to predict at least, a round in the 70s) but who still score in the 80s.  I even recently had a round with 9 GIR and a score of 90 -- which is why 95 - 2 *GIR isn't meant to predict any individual's score, but does still highlight the importance of GIR and ball striking. Which brings me to my next point, which is also @Shorty's next point:  yeah, 50% chipping and putting is not the way to go, certainly not long term.  Maybe with the goal of getting those traits to about an average 20-handicapper's level (without sacrificing approach shot strength), and then using the 15/20 time productively in future weeks to improve on them.  The nice thing about chipping and putting is that there is some low hanging fruit as far as getting competent goes, especially if one is building off the sort of short game shots that come from missing fewer than half of one's GIRs.
    • The people I noticed who got vaxxed early, some of it was they knew an inside person, other than knowing exactly which sites to hit and when. Like people who were fully vaxxed by February/March.
