What does "REALLY" really mean here? Should I count office face time only? Should I add hours if I check company email from home? Should I subtract hours when I slack off during office hours? Should I subtract hours I spend doing paid stuff that I count as useless tedium or overhead work? So, my answer is: It Depends. Paid face time: 8 hours. Work that matters to the product: <4 hours. Face time plus work-related reading at home: 9 hours.
