Where do these spread figures come to play? At what point in the game?

You give pen levels for the 6 deck game, so, at what point do they take hold? Is it at the pen level, itself? If so, I assume the numbers will be different if we enter the game at a positive count BEFORE the cutcard, correct? Again, I am assuming these numbers are MAX SCOREs at the maximum point of the game?

Sorry for my ignorance, but not quite understanding a spread at the cutcard since there will be no more play once we reach that point.
