Good so far. Let's also say that the cut card is after the 50th card in the pack.

This way, if your minimum bet is $50, you are putting $500 on the table in negative situations.

But what if you spread to 2 hands of 1/2 of a unit. For example, if you regular minimum bet is $50, you could spread to 2 hands of $25. This way you are only playing 7 rounds of $50, or $350 before the cut card comes out. You have eaten away an extra 3 rounds and spent $150 less money. Also, because of the slight covariance between the hands you are actually better off than playing 7 hands of $50 and Wonging out the rest of the pack.

Ah, but playing multiple hands in a positive situation will also eat cards, so you may get less hands dealt when you have the advantage. You will be eating away the few good hands you get while playing through the same number of negative hands. This is not good. Even with the proper bet sizing on your multiple hands (78% for 2 hands, 53% for 3 hands...I think) you could still be getting less money on the table in good situations. This means less profit.
This is why you must be very careful about your consolidation betting or card eating strategy. As I said below, improperly eating cards can easily overcome your advantage. Don Schlesinger's "Blackjack Attack" covers this in great detail.
