Steps to Reproduce

1. check its code

   	public double getAverageSessionCount() {
   		return _nsess / getEscapedHours();
   	}
   

Current Result

when _nsess = 1, getEscapedHours()= 0.02
its result is 50, which violate "the average number of sessions being created in an hour"

Expected Result

when it's less than an hour, treat it as 1 hour
