Player expectation of a positive count

How often should you expect a run of good betting opportunities.

I have been getting in some practise at a six deck game, one shoe was negative all the way through the shoe, the next wasn't much better, the next the RC never went beyond 3 then zero at the end of the shoe.

Counting is like sex - you have to be able to maintain it.

It's one thing holding a deck of cards in one hand at home and flipping them over in under 25 seconds. It's a different game at the tables when the cards are whizzing right to left and after a few rounds of hands you've lost it.
