Par-3 Course Handicap Factoring


xrayvizhen

Recommended Posts

I was invited by a friend to play with him on a nine-hole par-3 executive course. It’s part of a 50+ community where he lives and I was very surprised to learn when I got there it has been officially rated by the USGA; Index=26.8 / Slope=72. It's a nice course, well maintained, designed by Arnold Palmer with some challenging holes but overall, I found it pretty easy and shot an even par 27. I feel weird about posting the score onto GHIN as the resulting differential, .31, will knock my handicap down by a full stroke. Not that I mind that, but I’m just wondering two things. Is it legit and should I even bother posting. It just seems….wrong. On the other hand, by not posting, would that be wrong. I’m conflicted.

Technically, you're required to post it. Otherwise, you're a sandbagger. 😄 

Also, it's a nine-hole score, so it won't do anything on its own until it's combined with another nine-hole score.

Does the second nine-hole score need to be from the same golf course? Because if it is, it will be quite some time (like maybe a year) before I play that one again. And I can't come to grips how a score from a nine-hole par-3 course can be combined with one from a conventional course. It just doesn't make sense to me.

No.

It's just the next (or the previous) nine-hole score you post.

They combine them the same way they combine a differential from another nine-hole course. Or if you play the same nine holes twice.

How would you combine the rating of a par-34 nine to the ratings of a par-37 nine? Same again.

I guess I'm just curious how the math works when combining scores from two disparate courses like a Par-3 with a normal course. So the differentials at each 9-holr course are calculated separately and then added together?

Did you read the link I posted?

Cuz it's all right there.

I second this.

The GHIN app combines 9-hole scores all the time, whether they are the same nine twice on different days (or even the same day), Or 2 nine-hole scores six months apart. If you post a nine-hole score of any kind on ANY course that has a course rating and slope rating, it just chills in the system until you post another 9-hole score. 
 

@iacas

Is this why 18-hole courses have ratings for each nine holes? So one can post nine-hole scores and maintain and index?

An example would be if you played the front or back twice due to course maintainence or let's say you play front nine on one day and then play it again on another day.

This is common for players who can only play nine holes due to schedules at work or other reasons. There are many players who typically play only nine holes.
Such as after work or early before work.

    • Yes, the impact of training and stuff is somewhat unknown. What's not unknown is how many more competitors they'd have to beat. Jack played against club pros. Tiger faced stronger fields in all of his regular PGA Tour events than Jack ever faced in his prime.

    • Worked on my swing again this morning. @iacas had me tweak my setup a bit first. Get a little further from the ball, a little more bent over and a little more knee bend. Here was last week: And today Result is giving myself a bit more room and having my arms hang more vertical. I used the same arm feels in the drill, extending right arm and having the club go behind me, but we added a shift on the my left leg while lowering the club, then kicking my left butt cheek back during the turn. It looks pretty good in the drill. On a 50% swing, the butt is not quite getting there. There’s a Latin term for this I think, something like Incomprehendia Buttox. Need to keep working on this. The arms look better. Face on with the drill I’m trying to get more weight on the left side before doing the turn. This one could have had a more exaggerated weight shift. I also topped the little fella badly. 50% impact looks a bit better but not quite there. I rehearsed the weight shift better.   Did a few short pitches at the end of the session.  
    • The physical aspect of being bigger is one thing.  The most important though is the training today.  Kids start training for their sport at a young age and it has become very scientific.  Assuming the athletes of older generations also trained in the same way, the impact it would have is unknown.  There are professional athletes who have found that losing too much weight and gaining more muscle hasn't always benefited their game and natural abilities
    • Day 529, April 13, 2024 Did something to my right hip, so slow motion stuff with the backswing while simultaneously stretching/pushing that hip… It was hurt a bit on Monday, too, but the soccer game last night wasn't particularly wise, perhaps. 😉
