15/30 Payout Keys

I have been tryin' to memorize the new prop box payout keys for our craps tables.
Harrah's took us down to 15/30, we were 16/31- and that's what I learned in school.
So far I have the Horn Highs and 3 unit bets down.
It's a matter of re-memorizing some of the multiplication tables. The easy ones: 2, 5 and 11 in many cases; but 4, 7 and 9 in others, are not as easy for me. I feel like a Dork not being able to quickly multiply in some cases but if I can just remember, then I won't have to do the math.

On a side note- I am dealing 21 at the Flamingo tomorrow and I am going to ask to step in on craps on my breaks! Will help me to get used to their tables by the time I have my next Audition!
