This post is going to seem out of place if you read the above responses 1st.
I don't think I typed what I was trying to say, so here is another try.

I can't stand to hold my tongue any longer.
The house advantage of 5.2% is based on all possible bets being placed with the same wager on every spin. If all possible bets are not made on a spin the house advantage goes up considerably.
Example: If you place 10 numbers, you have the 5.2% house advantage going against you and you have the other 27 numbers going against you.

If any roulette table in the world ever held 5.2% for 1 year, heads would roll.
Same for the single 0 table that held 2.6% for a year.
The pit would be cleaned out, Casino Mgr, shift mgr, pit boss, dealers, soft count and maybe the pit clerk.
Why? Because somebody would have to be cheating "Big Time".
Can you beat a roulette table on a visit to LV? Yes!
Can you beat a roulette table by playing it everyday with any system? No!
I felt you should have the whole story.
Have fun with gambling. Limit yourself to what you can afford to lose. Big surprize, sometimes you win!!!!
