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.
