my supervisor put the whole of his methodology in an appendix in order to meet the word count - on the other hand one of the others here had a 2 volume thesis, but I think it was when there was no word linit. I've put part of the discussion of my methodology in an appendix, in order to keep the word count within reason, super wanted an elaboration, but I had no words left for that section. there is also a lot more to go inthe appendix and I think it could easily reach the same word count as the rest of it.
