I watch my tip bettors for inaccuracy in basic strategy, or counters for simply not paying attention and hitting by accident after a long day. I can speed the game up for non-tippers/counters that would make the count very challenging.

Let's take this last point first: Please, please speed the game up. If you think that this is an issue why do you think casinos decide to decrease penetration? To "speed up" the game? LoL

Here's a secret for you; more hands per hour at an advantage = MORE MONEY WON! So, please speed the game up.

Of course you're watching your "tip" betters. They're "TIPPING." You! And that's ok for you. However, if I, or anyone who is proficient needs a dealer to assist them if they inadvertently make an error, they shouldn't be playing in the first place.
