P student, ok taking serveral days would work out pretty good then.
Born, I said one day, because most people (HO's) don't have access to data loggers for a week at a time.
My area is 93 outdoor design, so if a unit doesn't keep up when we have 3 consecutive days at design, then the size is questioned. After checking everthing else.
Around here, most people set their stats around 72 and 74.
