Yes I assume Pratt/Beevers are the same incarnation. He got a life force boost from the Eye of Harmony at the end of Deadly Assasin which kept him going long enough to get to traken and set up his scheme there.
Rightly or wrongly i've also always assumed that it was a different incarnation to delgado rather than just an aged, degraded version of him. I've always liked the idea that he kept regenerating to try and escape the Daleks after Frontier In Space and finally he/she just burnt out from doing it too many times, too quickly.
