Scavenging itself would be a higher advantage than counting.
I wonder what the house edge is for someone who plays BS but never doubles or splits. I doubled and split for her when it was right to do so and won a majority of those bets. She wouldn't double 11 vs 6, or split aces. I found an AP opportunity by sitting next to a newbie who refused to double down or split, even after I encouraged her to do so with her own money.
Was in Pittsburgh this weekend for a football game.
