a very good question.
The short-term 9/6 job returns nearly 95% i believe.
That $20 is worth about $19.
Little different from what any one-armed-bandit will get you,
and if there is a difference, so what ?
Are you concerned about a 35 cent differential ?
According to the Wizard of odds, it's actually 97.47% for 9/6 jacks or better when u take out the royal flush and straight flush.
