In the meantime, I've been cramming more info into the chart and re-scaled to better handle cases with negative values.

I also replaced Correlation to Ratings with Typicality which measures how well the holes scoring distribution matches the prototypical scoring distribution for a hole with the same average.

Usually, low scores of Typicality come from too many 3s or from an island hole with lots of 2s and 4s.

So here is San Francisco Open 2018 Gleneagles Golf Course MPO again.

Distance generally appears to make the star pointier.

Definitely.

Since distance is almost always a limited resource, the art of design is to find the ways to make the star pointier without adding distance.

I'll let you know if I get bored one day and manually work through a round. I thought I read you didn't include scores with penalty strokes when you do your par ratings, maybe there is something similar you could do with a scoring spread analysis?

Do the Utah Open, or SC Masters Cup Golf course.

For par, I don't manually exclude scores with penalty throws. They just usually don't survive the crucible of taking only enough lowest scores to figure out what par should be. If there are enough penalty throws so that an expert cannot expect to avoid them, or if taking a penalty is the smart thing to do - such as teleporting to a very favorable DZ, penalty throws can be part of par.

I've never found a way to precipitate out ANY kinds of throws - drives, putts, or penalties - by just looking at scores, even if hole lengths and ratings are also available. I need a centrifuge, I guess.

Thanks Steve! This sort of stuff is a DG Stat Geek's wet dream.
Hopefully people take this sort of data into consideration when designing new courses.

...but I doubt many really will.
I don't think most "course designers" (in the loosest possible definition of the word), can really make sense of it.

I think the next step would be to take the really warped stars, look at those holes, and see "what attributes do those holes have that cause them to generate these unwanted results?"

If that can be summarized in a set of guidelines, sort of a "Do's and Dont's" of course design, perhaps we'd all benefit.

But I have a feeling, it's not so simple/easier said than done.
