It's a matter of time keeping. Because people are working longer hours, no one is time keeping properly. If I were to estimate Justine's hours based on when I see her working I'd put her at about 60+ solid hours a week. She hasn't taken a day off to my recollection. What she did with the exchanges normally a professional would charge a fortune to do. Remember that Steemit Inc failed to deliver for 4 years straight on exchange listings, and that's supposedly with a team. If you want to question, question those who make the big bucks but never seem to contribute anything.
