Yeah, it looks like the R1/R2 ratings dropped more than I would have expected. Unfortunately, I can't confirm that the unofficial ratings process matches what we currently do officially even on a per round basis. No one who wrote the software free has been involved with PDGA IT for maybe 8 years now. For example, I'm not sure that propagators who shoot more than 60 points below their rating (which many did at the USDGC at least one round) get dropped in the calculation like they do in the official process. This will artificially boost the SSA for unofficial ratings if this isn't done. However, the new web interface for events which is underway will address this issue and should produce ratings more consistent with the official process since we'll know for sure how they are being calculated.
