I don't color up, Thunder, but don't consider it "sneaking away". lol Maybe the casino does, I don't know, or really care for that matter. lol Since I buy in for very a small amount at a time, $100 which is 4 units, if the count tanks right away I probably only have a few chips to carry, so no need to color. If I have accumulated a good amount of chips I may color some before moving, but since I buy in as needed I usually dont have that many to carry.
As I stated, zg, I only really keep track of number of hands played, and just have a general idea of how long it takes me to get there. That way time doesn't get all muddled with 20 minute sandwich breaks, or bathroom breaks (legitimate, not wong out camo) or scouting time ect. I don't think 60 hands an hour estimate for me, is high, as I play a reasonable amount heads up and 1 other player, but will try to keep better track of it and get back to ya, bucko.
