But how did you calculate that you need 96 minutes per cycle? That's what I need to know

Also can you explain your math more clearly for those who are mathematically challenged. I don't see how you divide 9 by 90 and get 6. I get .1

First you need to match the units (hr/min).

60min = 1 hour
90min = 1 Sleep Cycle

convert 9 hours to mins. 9x60 = 540min.
so you have 9hrs = 540min.
now you divide 540min by 90 min. 540/90 = 6.
So, now you have 6 Sleep cycles completed.
