Well, here's some logic, in this article by Fred Renzey:
The Math Proves That Bad Blackjack Players Don't Hurt You
Here's a link to a bunch of articles written by Mr. Renzey:

I recommend all the ones about blackjack. (If I knew anything about poker, I'd probably recommend those, too!)
Maybe i misunderstood that example..I still think its a bad one that does not take into account the fact that you have a limited bankroll.
And just like those who suggest using progressive systems, it tends to assume that the mathematical probabilities will stay true.
That scenario can arise several times when you are playing and its indeed possible for 3rd base to take a dealers bust card several times consecutively.
Say the count was high each and every time he did this, throw in a few double down hands, splits and doubles after splits during a high count and your bank roll would take a huge hit.
Fine the mathematics holds that a correction is due that will help you win back your losses, but then guess what, here comes the cut card, its time to shuffle and the unplayed cards that would have given you the correction are now down the toilet along with the rest of this unbalanced equation.
Believing that math is about the same as believing in progressive system.
while the mathematics is somewhat true, it does not account for such issue.
I still will hold firmly to my belief that you are better off completely avoiding unnecessary unknowns. As IHATE17 said, you cant predict if a ploppy's play will hurt you or help you. Apparently its like flipping a coin. Well here is the thing, i am learning to count cards just so that i can win at the game on my own.
I dont need the help of a wacky ploppy to win if i learn to do whats right. If you all hold a person can win at blackjack by counting cards. He does not need outside help! The question still stands why should this person accept an unknown quantity that might help or hurt him.
If i am going to win, i dont want a ploppy to help me win because i am going to win anyway right? And if i am going to win i sure as hell dont need to ploppy to ruin my plays but spoiling the count and taking the dealer's bust card.
The key here is that the ploppy is not necessary to achieve your goal. But his inclusion has one negative aspect that has a 50% chance of hurting you.
Why bother with the ploppy in the first place?
