Keep in mind that the 90 minute cycle length is only an approximation. In my case it's about 75-80 minutes, but it varies from person to person.
I've been getting 4 cycles (about 5 1/2 hours) for about 7 months now - quite happily, I might add - but the times I've tried to switch to 3 cycles I've been tired the next day.
I'm not saying that 3 cycles can't work, just that at 5.5 hours per day I'm happy with 4.
