I'm not sure I follow that either, bartleby1. I averaged mine over the week and came up with 25% of my time, but I thought I was being generous. Perhaps they are looking at the total time, from collecting it, washing, drying, iorning (for those that do), and putting it away.
But if you spent 7 hours a day doing laundry, 8 hours sleeping and working, 1.5 hours for food consumption and we are already over. Maybe that's why there's not enough time in the day -- too much laundry!
