Why does Table 1 contain 2.9.11 and 12 when these predate the conference decision held July
2005?
"At the 2005 Kernel Developer Summit in Ottawa, Canada, it was decided that kernel releases
would happen every 2-3 months, with each release being a "major" release".

That decision simply ratified the de-facto process which was already in place; what really happened in 2005 was the adoption of the merge window discipline. The paper goes back to 2.6.11 because that's when the git history starts. That's when we start to have really good information about where the code is coming from.
