I agree with this unless what you are doing helps in general.
Historically, we ran a session every year for Georgia Tech because they ran the option. For the past few years, we have run a session for UTjr because of the pace they run. Those made sense because we play them every year.
On the UTjr thing, having two DCs really helped there. At some point Smart told Muschamp, you've got UTjr for the next 3 weeks, Schuman has the next 3 games. Champ was obviously involved in the planning for all the games, but allowing him to concentrate on that one game is a luxury we have when you have two really good DCs on staff.
