I don’t understand. The Master has regenerated more than the Doctor. This doesn’t even come close to explaining the regeneration incongruence. How can the Master regenerate more than 15 times? Is s/he/it from the same planet at the Doctor? This was an attempt to solve a loose end, and it just created a million more. We need something more comprehensive that falls within cannon, not something wholly outside of it.
