Cap Patrol - Handicap Evaluation

[jsgolfer]

Was looking at our clubs website and ran across this article about a new software program we just started using, called Cap Patrol,  and was wondering if anyone has heard of this and has has it actually spotted sandbaggers, as it suggest?

 

This genius computer program is designed to spot sandbaggers

---

Cap Patrol is a new computer program using advanced statistics to distinguish between scores, with the goal of spotting sandbaggers.

The example they gave wasn't a good one. The handicap isn't an average. The 75 would count, the 100 would not.

But… you could probably do something like this. Just look at the rounds, consider other rounds shot that day, tag which rounds are which (self-entered, entered by a tournament committee, whatever), and so on…

Couldn't sandbaggers just not submit a good score, and manipulate their handicap by not giving "genius" computer program data to analyze?

That confused me. 

The software might be good. The article is poorly written.

We have someone at my local club who is absolutely notorious for being a sandbagger.   And he loves it.  He'll take your money and smile when you say anything about it.   People are trying to verify if he actually plays all the scores he posts.   The thought is that he always seems to do well at our home club but on his GHIN there are a lot of scores from other courses that are, of course, higher.   Even with dropping it to 8, instead of 10, of your last 20 scores he can push out a good local score in a short period of time.

The other thing is that the prior club pro pulled up his history of posting scores and concluded that no one could beat their handicap the way he does at tournaments.  I would think that someone eyeballing that would be better than software trying to make a guess. Our home course has good players with a big variance in the scores because it's so tight and unforgiving.   Some of them could be flagged.

He also has a reputation for cheating.   People paired with him on the weekly money games or tournaments routinely get told to watch him like a hawk in the woods because "he never loses a ball, if you know what I mean...."

That's closer to the opposite of the truth. The software isn't "making a guess." It's following a set of rules, an algorithm. The biggest error there is that… a human made the algorithm.

If he's "notorious for being a sandbagger" I think it would be pretty dumb to play him for money.

It appears one of the primary goals of Cap Patrol is to give cover to the Handicap Committee if they take action against an alleged sand bagger.  The Committee can use the Cap Patrol recommendation for support of any handicap adjustment.

If a Handicap Committee is doing their job, a sand bagger is fairly quickly noted. He/she will win a couple times but outstanding tournament play is hard to hide. The real problem is a Committee not stepping in.  Cap Patrol might give them the needed nudge.

It’s come up a lot, but they won’t institute tournament handicaps and they won’t restrict him.   He pays his golf association dues and that gets him into tournaments that pay money.  Weekly games are simply paying your money and playing.  He’d have to be banned.  

He even has a pat answer.  He has told people that he just knows how to play our course because it’s his home course, and all those other scores at different courses are higher because he “doesn’t know the course”.

Some people view rules differently. Meaning they will try to get away with anything.

I remember reading something about that software, and couldn't help think "wow, shoulda thought of that!"  Pretty sure that if someone's routinely blowing away their handicap, the software would give data and percentages etc allowing a discussion to take place with the offender, armed with data/backup.

But unfortunately you're stuck, nobody's willing to address it, so the bad guy get's away with it.  Not sure how I'd handle it either, honestly. Maybe catch him cheating, somehow...

So I got a call from the Golf Committee chair yesterday and he told me I got flagged by the software.  The trigger he said is playing .4 better than your index in tournament rounds (which doesn't seem like much).  At the time they ran the numbers, I was a 6.4 Index and software said I should be reduced to a 6.0, and both indexes are a 6 HC at my home course.  I really need to figure out how to sandbag better.

So I checked my tournament scores on GHIN, 17 total, and my average differential was 8.9, and even if you took the best 8 out of the scores like a normal HC, it is a 6.7 average differential.  So I'm really curious what data they used and how the algorithm flagged me.  Maybe I'm missing something.

To me, this is one of the problems with reliance on computer evaluations, some people will rely on the computerized evaluations without really understanding how the algorithms are set up.   The program certainly can look for and identify anomalous data, but actions should be based on human evaluations of that same data.  In your shoes, I'd ask for a face to face meeting, where you can see exactly what the Committee is seeing, and compare it with your own research.

He told me he'd send me the data they used.  They aren't talking about reducing my HC yet, but that I'm on a watch list (double secret probation).

With 17 scores, the GHIN handicap formula would use the 6 best differentials (not 8).  If the program is comparing your GHIN index versus a Competition Index (using just the 17 "C" scores), they may have seen a slight difference, which prompted the inquiry.  Frankly, as you pointed out, dropping you from 6.4 to 6.0 doesn't make a whole lot of difference and really is not called for.

Come to find out they track data over two years, and between 2019-2020, I was struggling mightily with my game, and in the late summer 2020, I started playing much better and did really well in a bunch of tournaments before my HC corrected to where it is now.  The 2020 tournament scores will drop off over the year, and I should be of list. Unless I do well in more tournaments.
