The card handling device of claim 1, wherein the processor is further configured to automatically create and maintain a deck height table configured to store data indicating a deck height for different numbers of cards stacked on the elevator platform, wherein the data indicating the deck height includes positional data for the elevator platform. 6. The card handling device of claim 1, wherein the particular card insertion characteristic depends on at least one of deck type, amount of use, and handling of the un-shuffled set of cards. 7. A card handling device, comprising: a card input area and a card output area configured to transform an un-shuffled set of cards into a shuffled set of cards;a card gripper configured to grip cards from the shuffled set of cards;an elevator platform that provides a base for the shuffled set of cards during a shuffling operation; anda processor operably coupled with the card gripper and the elevator platform, the processor configured to: generate a virtual shuffled set of cards according to a random number generator;control the card gripper and the elevator platform to a grip position and create a gap for insertion of a card with a card insert system during the shuffling operation; andadjust the grip position according to a plurality of different corrective values indicating how to adjust the elevator platform from the grip position that are different depending on a number of cards to be gripped and a number of cards on the elevator platform. 8. The card handling device of claim 7, further comprising a top platform card sensor positioned below the card gripper and operably coupled with the processor, wherein the processor is configured to record a position of the elevator platform responsive to the top platform card sensor detecting a top card on the elevator platform. 9. The card handling device of claim 8, wherein the processor is configured to compare a measured position of a height of cards remaining on the elevator platform after the grip to a reference position of an expected height of cards remaining on the elevator platform after the grip and to adjust the plurality of different corrective values. 10. The card handling device of claim 9, wherein the processor is configured to determine the reference position based on at least one of a one-dimensional method, a two-dimensional method, and a combination of the one-dimensional method and two-dimensional method, wherein: only the height of cards on the elevator platform is used by the processor to determine the one-dimensional method; anda combination of a number of cards to be gripped and a number of cards on the elevator platform is used by the processor to determine the two-dimensional method. 11. The card handling device of claim 10, wherein the reference position is defined as RP=½(P1+P2)+C steps, wherein RP is the reference position, P1 is a position of the elevator platform resulting from the one-dimensional method, P2 is a position of the elevator platform resulting from the two-dimensional method, and C is a bias constant. 12.
