This is sort of my findings as well. My condensed version is: 1) Lowest cost to root. 2) Lowest Bridge priority (sending/upstream bridge). 3) Lowest port cost. 4) Lowest priority on the port of the upstream bridge. 5) Lowest port number on the downstream bridge. Ofcourse the decision process is only really interesting when you have multiple links to your upstream bridge. Cool post. This is sort of my findings as well. My condensed version is:
