based on the time left in the game and the score. there are too many possible combinations to list (for example, 10 pt game with 8 minutes left in game with slight increase as each minute passes, more in OT).
then again, as you pointed out, this is just speculation...
in the real world, players get more experience playing in grind time (close game) situations than they do playing trash/garbage minutes (blowout games). but BB is not the real world...
