For some reason, I decided to calculate Hole Length Variety for 289 courses for which I have hole lengths. This is a measure of how many different lengths of holes a course offers. One hole is 100% “different” from another if the longer hole is as at least 20% longer.

The actual calculations involve taking the log to the base 1.2 of the ratios of the lengths of each hole to each hole, rounding to an integer and then count the number of different integers using the Scoring Spread Width formula.

Anyway, here are the results.

The average across all courses was 6.08, which is about like having an even spread of hole lengths from 208 feet to 518 feet.

Here are the hole lengths (shortest to longest) for the courses that had the most variety (8.53) and the least (2.97).
