PDGA vs DGCR rating

Horsmanm's thread got me curious about this. Is there a strong correlation between PDGA and DGCR ratings (I tried searching)? Post both if you have them and let's see!

While I didn't renew my PDGA membership for this year, my rating was (I think) around 875. My DGCR rating is 882. While not perfect for me at least its close.

I think its very helpful for those who have never entered at sanctioned tourney event and those who would just rather not join the PDGA to determine what Division they should compete at if the do enter a sanctioned event. But you have to religiously enter your scores good and bad for it to be meaningful.

mine aren't even close. But, since i only put non tourney rounds in DGCR, and it's more based on casual rounds at courses I know it is substantially higher. My PDGA rating is based on my tourney nerves (suck) as well as playing in many tourneys at courses I've never played before.

PDGA 900. DGCR 929.

I just looked up the last 6 rounds I've loaded and compared them to SSAs that we gathered on those courses during the 2012 Worlds.

Course/Configuration: Nevin Short + New 11, Idlewild Long, Reedy Short + Par 4 on 13, Reedy Short, Renaissance Gold, Winget
PDGA Rating: 886, 952, 906, 929, 953, 922 = 924.667 avg
DGCR Rating: 934, 975, 931, 963, 919, 925 = 941.166 avg

The DGCR rating is higher than the PDGA rating on every course other than Renny Gold. I wonder what factor is creating the deviation; distance, level of foliage or OB?

DGCR Player ratings are derived directly from our Scratch Scoring Estimate....and, the SSE calculation has basically 1 variable that adjusts SSE for any given course....and there are only 3 increments in that variable. For any given length of course, there is Lightly-, Moderately- and Heavily- Wooded.

For a course on the longer end (say 6-7,000'), that can result in SSE's in increments of 6. For example SSE=48 for Lightly, 54 for Moderately and 60 for Heavily.

On a Moderately Wooded course, if it matched "perfectly", SSE would match SSA perfectly at 54. But it is a little less wooded it would be high by 2-3 throws (SSE=54, but SSA=51) and visa versa for if it was a little more wooded than Moderately (SSE=54, SSA=57).

Here is some data to look at from Pro Worlds 2013. The far right column compares DGCR SSE with PDGA SSA

You can religiously enter scores and it can still be way off if you play courses with lots of artificial OB or a lot of nine holers.

PDGA 885 & rising
DGCR 932

I do play a lot of nine hole rounds.
It was also an interesting exercise to compare sanctioned events ratings. I do think the tournaments with a lot of artificial OB's had the most discrepancy with PDGA>DGCR. I think the wooded courses work a little bit the other way. And definitely casual rounds run about three strokes better than tourney rounds for me!

So far, everybody's DCGR rating is higher than their PDGA rating.

Mine is almost 40 points the other direction. I'd suspect that the truth lies somewhere between those two numbers.

I only have six PDGA rounds. (How I'm seeing my PDGA rating, I don't know, as I'm not current). When two rounds from last November fall off, its going to plummet unless I can replicate them.

MY DGCR rating gets bogged down because I frequently play a nine hole course with a SSE of 21.3, and a course loaded with artificial OB (which the DGCR formula doesn't take into account) with a supposed SSE of 47.1. At our league there on Sunday, the best score was a 60. During our tournament last month, with at least sixty players, it only gave up five sub-50 rounds, and only about fifteen under-54 rounds.
