New World Handicaps 2020


Augustok

Recommended Posts

Does anyone know how the math will work? Now the 10 lowest differentials are added, averaged and then multiplied by .96 to get your index. Looking at my most recent revision scores my index is 16.5. If the new handicap in 2020 is to be based on 8 best scores of 20 instead of 10 then averaged if it is still multiplied by .96 my index would be 12.8. Seems like a big difference.

It's still going to be based on differentials, not scores.

 

Average of the 8 best differentials instead of best 10 and no more multiply by 0.96. The other big difference is ESC is now based on max NET double.

I looked up my last 20-scores at GHIN. If that’s the case my current index of 2.8 drops to 2.4. I would think that it’s unlikely anyone’s handicap is going up with this method.

There may be larger or smaller differences in other parts of the world where averaging is not currently used.

Does anyone have any information on the "abnormal course and weather condition" calculation?

 

Curious how that's going to work. It it factored day of to assign strokes, or after the round to enter in the system?

You can find the calculations done for the Computed Buffer Adjustment used for competition scores in the EGA from the link below (page 45). The CBA is calculated when all scores have been returned and the results are finalized. In the new system the calculations would take place at or some time after midnight.

 

The system simply looks at the scores for the competition/day and if the scores are unusually good or bad, it is assumed it was due to the conditions and the scores therefore require adjustments for handicap purposes. Of course the formulas will most likely be different in the WHS.

No, that's not confusing at all (to do in ones head). I write some software to track leagues, and was just curious to get a heads up on the calcs... and run some test numbers to inform the users. I'll wait to see how it shakes out (is published) in the WHS before I do. I really hope they don't wait until Jan to actually publish the cals.

I just ran my last 20 differentials.

 

Under the new method (best 8 of 20 averaged, no 0.96 multiplier) before rounding my index would be 18.500

 

Under the current method (best 10 of 20 averaged, 0.96 multiplier) before rounding my index is 18.432

 

So after rounding, the new system would make mine go "up" from 18.4 to 18.5 but that's just an illusion of rounding. Basically it would stay the same. I had checked this earlier in the summer (with a different 20 scores posted) and at that time the difference would have been to stay exactly the same after rounding.

I haven't bothered to check mine, but I'm sure it will be close enough to not matter.

 

One thing that I still haven't seen clarified is whether or not hole by hole score posting was going to be a requirement of the new system or not. I was in a discussion with some guys on another forum who seemed to think it would be but I haven't seen that confirmed yet.

In the discussion you refer to, the discussants seem to believe that their own pet ways for the system to work are going to be forced on everyone. Including hole-by-hole posting.

 

Due to the fragmentary and provisional (often inconsistent) information trickling out of the various world handicapping bodies, people tend to see what they want to see in the tea leaves, if you know what I mean.

 

The reality is, the supposedly standardized World Handicap System will be highly customized by every different organization doing handicapping in their own country. I doubt that something like hole-by-hole posting will be uniformly implemented. Even much more important issues (like attested scores) are as far as current information indicates going to be left up to local authorities rather than standardized world-wide.

This is my understanding as well, the calculations will now be the same around the world, but significant differences will remain. My personal hope is that the 2020 changes will be a first step, and we'll see additional steps taken over the next decade or so to truly unite the handicaps worldwide.

Which is in effect no change from the current system. Today hole by hole is required by CONGU (makes sense since they are basically using attested comp scorecards) and it is optional under USGA.

 

In 2020 it will be required by CONGU and there's nothing about the new system that requires it to be anything other than optional under USGA.

 

As DaveP correctly says, this is mostly a handicap formula reconciliation. Reconciling all other aspects of handicapping among the various authorities is left for future revisions.

I thought one of the key tenets of WHS is the move to net double bogey as ‘maximum score’ and doing away with Esc? Has this been changed? Otherwise I don’t see how you can compute ndb.

You would make the player responsible for knowing when he's made net double bogey. Just as you current expect him to know that 8 or 7 or gross double bogey is his ESC limit.

 

Of course in the Real World most golfers on GHIN will carry forward just like today. They will pick up and say "give me a 6" no matter what their course handicap.

At this stage, we don't know how Tournament scores will be handled in the US, or whether they will continue to be monitored. There IS a procedure to decrease the handicap index based on individual exceptional scores. There will also be a cap on handicap increases.

There's some information here, mostly in broad-brush form:

NO, at least not in the way it is understood right now. The maximum hole score will be par plus any handicap strokes allotted for that hole plus 2 more, the gross score that would result in a net double bogey. The term "Equitable Stroke Control" will be gone completely, but the same concept, a limit on the score for each individual hole, will remain.

Where a Course Handicap is more than 54 and a player receives 4 or more strokes on a hole, the maximum hole score is par + 5 **for handicap purposes **

So how on earth can you achieve this if there is not to be mandatory hole-by-hole scoring?

Thanks for the clarification, I hadn't read that previously, and its not mentioned on either the WHS website or on the corresponding pages of the R&A website. For most of us, "net double" will apply, its only a small percentage who will have a course handicap over 54.

Honestly, if someone is playing off a 54 handicap who on earth cares if they apply the wrong "max hole score"?

 

Why on earth (as you might say) should a 6 hcp posting 250 rounds a year be forced to type in 18 separate hole scores every stinking day just so that some guy shooting 150 can use his correct max score of 9 instead of 10 on a pickup hole.

 

That's what you hole-by-hole guys fail to account for. That core group of golfers who play a lot, always shoot around the same scores, have middle-to-high single digit handicaps and whose handicap is easy as pie to compute and track. There's no percentage in implementing a system that needlessly annoys that constituency in search of some imagined perfection for imputing arbitrary max-score numbers to high-handicap hacks who pick up multiple times every round.

Your question is a little like asking "How can we expect people to add and subtract without using an electronic calculator?" You expect players to understand where they get strokes. I know, too many won't understand, or won't care, but its really not rocket science to know your course handicap, and to allocate the strokes appropriately. And of course, using a computer to do that will make compliance better, although it may also mean that fewer rounds will be reported, especially within the US handicap area. We'll wait and see, perhaps hole by hole reporting WILL be a requirement in the US.

That replacement for ESC is going to befuddle about 75% of golfers. I fear it's going to make indexes less accurate.
