Way too good to be true, what am I missing?


Recommended Posts

Hey all,

The coronavirus got me back into golf after a long break. I've been playing nine holes almost every evening since May.

I mostly play alone, so I have been using my handicap from when I last played and I've been keeping strict score.

I just entered my last 20 rounds into a World Handicap System calculator and it's saying my index is 11.7, which is way better than I ever was before. Have I made a mistake somewhere? Would love an extra set of eyes or two on this.


Two free calculators for computing a golf player's course handicap and the player's World Handicap System (WHS) handicap index based on their past scores. In addition, explore hundreds of other calculators addressing...

is the site where I've entered my scores.

Cheers.

It looks to me that the website you're using is treating your 9-hole scores as 18s, and averaging the best 8 differentials.  You might try it by manually adding the scores to make nine 18-hole totals and see what you come up with.

Yeah my 9 hole caps, if extrapolated to 18, would result in a much lower cap. I can shoot low (for me) 9 hole rounds, but it's much harder to string them together for 18.

Something similar happened to me two years ago. I played frequent 9 hole rounds after work in summer, and was scoring between 40-45. When I played 18, I was regularly shooting in the 90-100 range. Over that summer, I think my handicap dropped from around 23 to 18. Once winter came around and I didn't have daylight after work to play, my handicap slowly returned to the low 20s.

I use that website to track my handicap.  (It does not account for playing conditions or ESC) But beyond that, I analyzed it up and down and independently checked with a phone app in early 2019.  It is accurate as far as I can tell.  But I never play 9 holes.  I recommend taking Dave’s idea.

No Mistake, here is your link showing the Average Differential.
Basically, I see the rating and slope being very low.
Is this an Executive Course ?  Also, what is Par for the Nine holes you are playing.
If you play an 18 hole course, the rating is different for the front and back.
And, I'm not sure if the new software "Combines 9 hole Scores anymore" It used to.

As an example, I changed the Rating and Slope to a more difficult rated course, which shows a Diff "7" on a score of 44.

I took this to be a moderately easy 9-hole course, and the scores were each for 9 holes.  The resulting handicap is for 9 holes.  Double the number, and you'd get 23.4 for 18.  The new USGA systems (GHIN or any other) do combine 9-hole scores in the order in which they are played, but I'm not sure that online calculator recognizes them as 9-hole scores.

Interesting, Never even crossed my mind it would calculate an index for only 9 holes.

I'll go into the calculator and enter either combined scores or several 18 hole scores similar to his scores and check the outcome.
Guess I could copy his scores to another calculator and see if it come up with the similar results.

I think you've misunderstood the OP. @finitesoup is wondering why his handicap is so low, and the reason is because it's a 9-hole handicap calculation.

This handicap calculator is bad. Or out of date. I combined your 9-hole rounds into 18-hole rounds and used it to calculate your index, which gave me 27.8... but that's because it's using the average of the lowest 8 differentials, which is incorrect. There are 10 18-hole differentials, which means your index is calculated based on the average of the lowest 3 differentials, which is 24.4.

His average round for 9 holes is 48.  Par is 36.  So, he is averaging +12.

If you take the 10 best of his last 20, average round is 45, which is +9.

+11 handicap seems right in the correct range.

Not seeing what the issue is, and it's certainly not anywhere near 100% off

That's not how to calculate a handicap index.

It is the shorter/easier 9 hole course at our club. Not sure if it would be considered an Executive Course as it does have a par 5 and 4 par 4s. Par is 33. I was actually wondering why the calculator didn't ask for par as in my understanding it's necessary for the new WHS.

@finitesoup  here is another site to try - https://www.free-online-calculator-use.com/golf-handicap-calculator.html

Keep in mind you will need to make any necessary adjustment to scores over "Net - Double Bogey" when entering total scores.
Below I enter your scores and here is the result. Note scores were combined in the calculation.

Also, when playing at a nine hole course, you receive half of you Index for a course handicap.
I'm guessing in your OP, you thought the Index was an 18 hole Index?

I did think it was an 18 hole index, makes much more sense that it's for 9 holes.

Thanks everyone for helping me figure it out.

The calculator you used was for calculating your handicap index. Par is only needed for calculating your course handicap.

His average round for 9 holes is 48.  Par is 33.  So, he is averaging +15.
If you take the 10 best of his last 20, average round is 45, which is +12.
If you double that for 18 holes, he is around +24

Remember, under the current rules, we only use the best 8 of the last 20.  And we use Differentials, the raw score times 113/Slope.  But yeah, its somewhere around 24.

    • A strange round of golf yesterday. I played from the red tees (plays just 5350 yards).  My ballstriking is not very crisp these days, but hopefully I can sort that out soon. It was a round of two halves, as usual. Front 9:  Could not hit fairways or greens at all on the front, 2/9 greens and 2/6 fairways, but still shot +2 on the front. That includes 2 shots in the bunker on hole 4, a horrible misshit that lead to a double on hole 7, topped my driver 80 yards twice and the only 2 fairways I hit were with short irons in hand. 11 putts on the front 9 says a lot about that tretch of holes.  Birdie on both par 5s on the front is allways nice.  37 shots, par 35 Back 9:  A little better ballstriking even though I hit 2 shots OB, leading to a tripple and a double, 4/7 fairway and 4/9 greens. The short game was more off here and I left a couple of chips a bit short. 17 putts is not as good as I'd like it to be. 1 threeputt, but I think I would threeputt from there more often than not, as it was a 60 foot downhill putt with a lot of break where I gave it a little to much speed. Birdie on hole 15 (short par 3) and on hole 17 was nice, and I missed a short birdieputt on, the tough par 3, 11. Had 165 yards in after a decent drive on the par 5 18, but managed the top the approach and miss the green from 90 yards after that and walk off with a bogey after also missing the 5 foot par save. 44 shots, par 37.  81 shots is not bad, but I make to many misstakes from tee, making golf a lot harder than it needs to be. I hit driver on 8 holes: 1 fairway hit (265 yards), 1 OB, hit short and low slices mostly except from the two topped 80 yard ones, avg. 240 yards today. My drives are usually 270-320 yards depending on wind and course, so my driving is not where it should be. My short game is not perfect, but it's certainly better than my hcp right now.  Playing a round at an away course today. There is a curse hanging over that course that needs to be lifted. Good luck me 😉  
    • Our range closes early on Sunday to do a “clean pick”, and reopens at 11:30 on Monday. It is mowed early Monday. The course is closed until noon on Monday’s.
    • If you do get a new putter, get fit first. Try a bunch out at a golf store and see what kinds you like first. Then find a good fitter to get your numbers down, length, lie, loft and overall weight. Heavier putters can help with distance control for some folks. Also, a different grip size may help even if n your current putter. For distance control, having a consistent rhythm helps. In my visit to Erie, Erik had me work on increasing my rhythm a bit because I was a bit too slow and it varied. I have a tempo app on my phone and set my rhythm to 2/4 time at 72 bpm. When I practice putting, I first work on my rhythm for short, medium and long putts. Then I work on read and start line. This drill can help too.  
    • Day 68, August 1, 2021:  My backswing is still too long. I’m trying to get it shorter I look at it on film and it’s way too long, did some pitching length swing length feeling swings, so it’s probably half to three quarter length backswing.
    • I think he’s making a huge assumption that something he feels makes him do something, will translate to anyone else. I think tips like these come from instructors who confuse the concept of what’s natural anatomy wise isn’t natural function wise if that makes sense.
