If unofficial results and ratings are gone from the site, they aren't saved anywhere for me or anyone else to find them. The good news is that retaining unofficial ratings online until the official ones are calculated is on the list of technical enhancements for our website staff & volunteers. I've never checked to see if those online website archive sites might have a snapshot of our PDGA site from a few weeks or months ago to bring up the unofficial ratings. Another option is to look at other SSA values online for that course and estimate your ratings from that (
