Jim I totally agree with your principles. The main difference, in operation not philosophy, is that most (good?) practitioners include 'all of the above' before getting to a classification stage.
For example, the selection of which blocks to estimate in the first place is done on the basis of all existing geological knowledge plus assumptions about continuity etc. So, a block is not even estimated unless it is pretty adequately known anyway. The use of a single criterion to distinguish the line between measured and indicated resources is almost a formality and probably depends more on the target audience than any other motivation.
