Another doctor who theory

This comment was posted today to that article I listed in the last post...

If you do what he says and go back and look at all the old stories you'll notice that after the very first regeneration, the one form Hartnell to Troughton, the Doctor explains that what happened was a "...function of my ship, without it I would die"
If you then go look at stories such as Wargames The 5 Doctors, Underworld, and the last 3 episodes of 2007's series three, you'll notice that the Timelords have the technology to induce endless numbers of regenerations through machines that they even give away to lesser races.
From watching these episodes it's a fairly straight forward assumption that they can, if they choose, forego using their OWN regenerations (of which they come equipped with 12) IF they have the technology to hand, (ie The TARDIS)
By simply lo oking at ALL the evidence of what goes on round the regenerations we've seen, (and not just listening to Engin) you can conclude that any regeneration that the Doctor has undergone while in proximity of The TARDIS was basically the ship doing what it did in Tenth Planet, and essentially using IT'S power to regenerate him.
In answer to the next question...
Why didn't the same thing happen for the Master?
Simple... while the Doctor stole a TARDIS with a faulty navigation and chameleon circuit, The Master stole the one one Clara told the Doctor to avoid, the one that had a faulty "regeneration" system...
Prove me wrong...

Me: excellent! I love this. It took a lot of effort to think this one up. I just wanted to share this Guy's idea!
