1. A method for forming a randomized set of cards, comprising:

  • generating, with a random number generator (RNG), a random delivery order of a stack of shuffled cards;

    determining, with a processor, an initial grip position of an elevator platform of a card handling device, the elevator platform configured to move relative to a position of a card gripper adjacent a card insert system;

    determining, with the processor, an expected height of a set of cards remaining on the elevator platform;

    measuring, with a top platform card sensor, an actual height of the set of cards remaining on the elevator platform;

    determining, with the processor, an adjusted grip position of the elevator platform according to correction values indicating a magnitude of adjustment required to move the elevator platform from the initial grip position to the adjusted grip position based at least in part on a difference between the actual height of the set of cards remaining on the elevator platform and the expected height of the set of cards remaining on the elevator platform;

    moving at least one of the elevator platform and the card gripper to create a gap in the set of cards for insertion of a card at the adjusted grip position; and

    moving the card into the gap in the set of cards with the card insert system.
