It could be very fine-grained by market niche or website type - but I think it more likely it to be focused on a search phrase taxonomy. The search term measurements gained would be a lot easier to integrate into an overall approach to generating SERPs. However, this really does get out into a very speculative area.

My main point is that we might apparently see many different algorithms (as many people have already assumed) when there's really, essentially, just one algo that naturally adapts to varying practices. It would also give results that naturally balked at being reverse engineered because the tolerable variances would vary widely according to the search term.
