I was playing at a game of 6D with penetration of about 5-1/4 decks over the weekend. Given the greater likelihood of reaching the pivot point ( + 2 TC ) at some point during the shoe of that depth I reasoned that I should stay in the shoe longer with a low count than I would if the penetration was only 4-1/2 decks. This casino also had low limits so it did not cost so much to stay in as long as 3 decks. Conversely if I find myself at a table with a shallow penetration I will leave earlier when the count is low. Does this make mathematical sense ?
