I read over it quickly, a lot of great data. One thing you may want to consider is the difference multi-hop BGP has in your data collection. For several years, router vendors give priority to locally sourced routing packets on local interfaces. But on multi-hop sessions, I believe that prioritization is lost which may show up as more instability than is actually present at the local BGP exchanges.
