A typical sleep cycle is 90 minutes. If you wake up during the wrong part of the sleep cycle, you’re going to feel tired. 6 hours would likely leave you feeling better than 8 hours. 7.5 hours would feel better than 6.
Though, allotting 8 hours is a good idea. It accounts for the time it takes you to fall asleep and bathroom interruptions.
