That theory does make sense to me. But yes, 90 minutes is not a universal, it's a guideline average, I think.
There's this cool $300 alarm clock I've found online (that I want just for its coolness, of course, but can't possibly justify) that senses those cycles for each person and times itself to wake you up at the end of one. I'll post the link later if I can find it.
