Oh, it does look like I got it wrong. I actually thought that the edge would be the same as your win/lose ratio in the long run.
I am still confused. Here's a quote from Gamemasteronline:
"For each increase of 1 in the true count as figured by the Hi / Lo counting method, the player's advantage increases by about .5% in the average Blackjack game. If the casino has an edge over the basic strategy player of .40% (6 decks, double on any first two cards, double after splitting pairs, dealer stands on A-6), it takes a true count of just about 1 in order to get "even" with the house. Being even means that the player who utilizes proper basic strategy will win as much as s/he loses -- in the long run -- at a true count of one. A true count of 2 gives the counter an edge of .5% over the house; a true count of 3 gives the player an edge of 1% and so forth."
Doesn't this mean that a player is expected to "win as much as s/he loses", with regard to the number of hands? So, what is the definition of an edge?
