We have been making changes to the donor ranking on the Stanford stats pages to work to reconcile them with the 3rd party stats. The central issue at hand is how does a given stats system handle accounts with multiple passkeys. A more detailed discussion can be found in this discussion thread.
We are working directly with 3rd party stats to come up with a solution that works for all. For now, we have made one change which brings them closer, but not completely in agreement. However, donors who pay close attention to the Stanford site will likely see a big change in their ranking. We're posting this blog post to give donors a heads up on this issue and some information of what's going on behind the scenes.
