I know this is slightly off the original topic of this thread, but I wanted to add this small bit about the Fibonacci Sequence. I'm not an anatomist, but from the research I've done on the Fibonacci Sequence and the Golden Ratio, I've found exmaples of these throughout the anatomy of the human face. The outer ear and the cochlea, for example and at least in their idealized forms, are examples of the Fibonacci Sequence.
So, this makes me wonder if the reason why Fibonacci-based delays seem to work regardless of tempo is because, instead of being synchronized to the tempo, they're actually synchronized proportionally to the human ear. Anyway, that's my far-out thought for the day. I have no idea if this is what's actually going on…
