i think minor adjustments could be made, but believe the concept of the current scale is correct.
lets take a 5 star #1 ranked overall recruit that lives in southern california. why should the east coast schools get to pay the same as UCLA, USC, or any other local team for home visits and campus visits. obviously, the local coaches can drive to see the kid on a scouting trip, or to a home visit, and even drive the kid in for a campus visit. the east coast schools are flying cross country, staying in hotels, etc.
the model is in place, it may just need some adjusting.
