For 2020 DGPT - Dynamic Discs Open/Emporia Country Club/ECC Longs; 18 holes; Par 65; 10,980 ft.

Given a group of six players rated 970, 980, 990, 1000, 1010, and 1020 this course will assign a lower score to the higher rated player an average of 21.14 times out of the 30 possible pair-wise combinations of players. This places it at the 39th percentile (i.e. in the best half) of the courses I've studied.


Here is how each hole contributed.

It would appear the chart confirms that a player's golf distance is the most important factor for sorting skill levels?

That would be an unjustified conclusion, though not necessarily wrong.

What can be said is that on this particular course there is a tendency for longer holes to contribute more to the ability to sort players by rating. Because longer holes generally have higher scores, that could also be stated as a tendency for holes with higher scoring averages to be better at sorting.

On this course, the relationship between length and sorting ability is actually stronger than the relationship between average and sorting ability. Perhaps pumping up the scores of shorter holes was done in a way that was not as effective as lengthening those holes would have been. Maybe.

Since there were 45 players who played all three rounds at both DDO and TPC, I did a little comparison.

For Scoring Spread of total scores, DDO did a better job, with a scoring spread of 24.35 vs. TPC's 22.59. To put it another way, the typical player at DDO was tied with 0.85 other players, while at TPC they were tied with 0.99 other players.

Because single-point scoring spreads can be quirky, I also looked at how the courses would do based on 10,000 simulated rounds, with scores for each hole picked randomly from all three rounds.

DDO's averaged a score of 65.87, while TPC's average was 56.00. In 100% of the simulated rounds, DDO had a higher average score.

DDO generated an average scoring spread of 15.47, beating TPC's average of 12.71. In 94% of the simulated rounds, DDO had a better scoring spread.
