How much unsupervised time do your kids get in a normal week?

my whole childhood I was unsupervised for 90% of the day only time I was was at school (my parents worked very early and very late) i raised myself. I would say it is good for kids to have a lot of unsupervised time but not too much. Depending on the age about 2 maybe 3 hours a day. Unless its a school day then only a hour and a half.
