Old Welsh Guy: "There you go Bob, I had a word with my Mate Matt Cutts abd he has blogged this just for you..." Yes I read that post and it made a couple of points clearer for me. You were using the everflux the same way Matt defines it. From what I read the index is update daily and rankings change to a minor degree because of the daily updates. I would take it from his statements that RPR and BL are factored in daily. I had read GG state this some where else but for some reason I was still under the impress that RPR and BL would done in batches and not daily. Thanks for clarifying that.
I have a competitor whos site speaks for itself. Check the backlinks vs PR and SERPS; http://www. accessoriesthatrock.com Makes for an interesting case study, definately outside the norm but proves a point. If I made a couple links it might hurt the PR. Great serps, and not from backlinks. Remove the obvious space
