OK, maybe I am too OCD for my own good, but do you/should you count your commute to the casino when calculating your hourly win rate?
It normally takes me 20-45 minutes to get to the casino, 15-45 minutes on a wait list and 20-45 minutes to get back. All told that is 1-2+ hours. If I actually included this my 6-8 hour playing sessions go down in profitability by up to 33%.
I know no one lives at the casino and I am not playing during the commute, but if we are strictly talking about the "value of my time", the commute is there.
