2 at a time or just a glance will do
Counting for as long as I have, I can not help but count. Generally, I begin counting two cards at a time skipping neutral cards. Often they will cancel each other out. I found out many years ago that when I have a conversation with the pit, waitress or some other distraction, I can just glance at the table and adjust the count instantly with perhaps 15 cards on the table. When I first realised this, I tested myself at home many many times and have confidence today in just looking at a table full of cards and instantly adjusting. I know this has convinced suspicious pits in the past who started long conversations with me, thought I would lose the count if I was counting, and I continued with my play (if the shoe was juicy) and it never resulted in a backoff even when I went to max bet.
