If I offer a kid minutes to trigger the "wants to play" preference to G/VG, does the effect of that added preference retroactively apply to all actions performed prior to the offering of minutes, or only from that point forward? (i.e.-is it optimal strategy to offer the minutes immediately upon unlocking them so that you get an added boost to subsequent HV/CV actions? Or if it's a player I might want to attempt a redshirt on or who I'm not in an immediate battle for, is it possible to hold the minutes as an "ace in the hole" to get a boost later in recruiting beyond the mere bounce the offer would give?)
