It wasn't a firm minimum, it was "at least approximately." So I am sure 80% pen won't be impossible to find. What I found curious is that all hands are to be called dead if the dealer sticks a non-ten or ace in the hole card reader, and it conveys info to the players, like the "no peek" device. If a dealer really wanted to cheese a player off they would be within their legal right to check their 6 up in the reader when the player has a bj. Oops, you know I don't have soft 17 now, dead hand!
