How the hell do you measure it? I don't know how long it will take me to fall asleep, so how the hell do I know what time I should set the alarm to.??

The alarm is always set for ten mins. Sometimes I'm out in under two mins and sometimes I think I can't fall asleep just to be snoring when the alarm goes off. If I get interrupted(rarely) I just restart the alarm.

I personally don't think the sleep time matters, but the switch off that allows everything to reset.
