360 miles is the big threshold. I don't know where the chart is either, but there is a jump in the cost of home visit (HV) and campus visit (CV) outside 360 miles. It's not ideal, but you can see the differences in cost when you look at your own recruits. for instance, if you are in a battle with a guy who is 400 miles from a recruit, just look at your list of recruits (or do a search) and find one 400 miles away to see how much HV or CV will cost him…. then you can budget accordingly.
many say that CVs are more cost effective when you are more than 360 miles away from the recruit...
