Honestly, I think to really be able to get at the potential underlying mathematics, we might have to take a step backwards. The problem with using rating system features like SSA for these kinds of...

Edit on the above: I should probably mention that I actually think there's possibly an entirely different (again, stepwise) reason for break-away round ratings: the rare course/layout where players...

I would suspect it's partially the 'luck' factor, and partially the stepwise issue. In the PDGA system, there is a linear equation (actually there are two of them) that determines the number of...

TrueSkill, similarly, can accept the event results of a full field, but only as a rank-ordered (place) list. While this method is definitely throwing out potentially-valuable (round score) data, it...

Rating system like Elo/Glicko/TrueSkill are actually able to handle higher-variance (e.g. environmental variables) results reasonably still, they just need an adjusted (i.e. lower) 'k factor'. The k...

Hi Jeffboi,

Absolutely, individual SSA's are only directly applicable to a course and layout (as well as course condition), and depending on how many propagators were involved (and how many rounds...

Hi Lewis,

I just realized that this project *might* be able to help answer two mathematical questions I've been trying to answer lately.

1). Are your statistics able to suggest a (constant)...

In my opinion, the absolute worst way to lose a (second) disc is doing the exact same thing that got the first one lost. :wall:

I played Wilder DGC (Newport, OR) a few months ago, in light fog and...

*hehe* I know it's a ghost-town, but it also still has more Oregon viewership than DGCR does. :P

Edit: for tournament players, I should say. It's still where most folks go to figure out the Oregon...

This seems like a distinction that opens up a big grey area. Restrooms, for example. At some of our events, we have been required (by the parks dept.) to rent porta-potties. Sometimes we haven't been...

There are actually a variety of threads here where the workings of the PDGA rating system are detailed (I've contributed to some of them). From what we've been able to glean,...

Hi Chuck,

Yes, I remember you mentioning previously that simply reducing the overall number of propagators doesn't produce more accurate ratings. That's not really what I was suggesting, though....
