I don't think that my perception of it is more complicated as opposed to yours. In fact I believe it's the same principle, just explained with different tempo's. It reminds me of a question I asked Gavin a couple of months back regarding Time Flies. Do you feel it like 6/8 or do you feel it like 4/4. Both have different tempo's but the end result would be the same. This is pretty much the same I think. I feel the tempo slower, you feel it faster. Both are "correct" I guess, though the feel is different.
Not sure if I understand the latter part. Are you saying that if I would consider the whole piece in 5/4, I would end a little earlier? If that is what you mean then I should say that I don't regard the full piece as 5/4. Though I admit that wouldn't hold up with the principle of Occam's Razor itself…I do understand what your saying, the only problem is that with 2 measures of 5/4 (90 bpm) you get 30 triplets, and with 4 measure of 4/4 (120 bpm) you get 32 8th notes, which at these respective tempos the triplets and eighth notes will line up perfectly, but your way of looking at "Occam's Razor" will come out a little earlier because the measures aren't quite long enough.

Did that explain it better?
