// over Denominator calculation with the new Session Data. In short, this is not a reliable system for checking Achievements on the
// Server in real-time, as you only get the resulting Float *after* the client sends the data to Steam and the Steam Database has
// time to recalculate the new average.  The latest Float Value is only valid in OnStatsAndAchievementsReady and should not be
