AFAIK 7-9 hours is the commonly used range, anything less than 7 hours or anything more than 9 can have detrimental effects on how well rested you feel after waking up. Where did you get the notion that adults need exactly 8 hours on the dot?

It really is variable. My number is closer to 9, so even nights I get my "good 8 hours" I still end up with a sleep deficit by the end of the week.
