It should definitely not be so simple as how often you set your tempo to uptempo. If I am the game developer, no way do I want to incentivize coaches to game the system to exploit a simple criteria for recruit's preferences. Recruiting with preferences should be about finding the recruits that are good matches for your system, not gaming a simple system to get the recruits you want.
It is reasonable to say a team shouldn't be penalized by the opponents decisions. A good compromise here would be to tweak the formula, whatever it is, to account for the opponent's tempo. If the baseline for very good is 80 possessions per game, if the formula can be adjusted down to say 70 for when the opponent chooses slowdown, and 85 when the opponent chooses uptempo. So X(.875) for opponent slowdown games, X(1.06) for opponent uptempo games. That keeps the principle in place, that a recruit is looking to play on a team built to go uptempo, as part of its overall team philosophy.
