"People who do surf the Internet for fun at work â?? within a reasonable limit of less than 20% of their total time in the office â?? are more productive by about 9% than those who don?t,? says Dr. Brent Coker, from the Department of Management and Marketing."
9% more productive but lose 20% of time. Doing the math youre still only at 87% work capacity. lulz
I think they meant they were 9% more productive total not per hour or whatever
