I got a surprising amount of housework done. In addition to vacuuming the living room and giving the kitchen a once-over, I got the dresser put together after V left.
I figured out the formula for number of monitors needed on any given day: Number of employees plus number of employees in need of a second monitoring session = total monitor sessions to do. Total monitor sessions to do divided by shift hours (that is, the actual working hours of the shift, if people are coming in at three and going home at eight it would be four to four and a quarter hours, because there's break to consider, and also monitor setup time, which is 15 to 30 minutes) and then divided again by the Magic Number 4.5, which is how many monitoring sessions per hour we the monitors are supposed to get.
Also, I guess there's joy in Mudville tonight.
