This chart is the one that shows the how much each hole contributed to the information contained in the set of final scores (size of bubbles).
The x-axis is again a measure of how many different scores the hole handed out. The vertical axis shows how well the holes sorted those scores in a non-random way.
All these are for Santa Cruz Masters Cup presented by Innova - National Tour 2018 MPO only.
Two things are notable about the DGC charts. One is that so many holes contributed nothing or even negatively to the information content of the final results. The other is that the chart for Rd1 doesn't look like the chart for Rd2 at all.
Why?
A fairly narrow range of really good players + hardly any big scores (only one hole in one round had mostly 4s) + the well-known tendency of DeLa to influence scores in its own way.
