Is there a reason you placed the 4,5,9,10 instead of buying them? Not criticizing, just asking. On the azure machine here a bought $75, 5 or nine pays $1.87 more net than the place, and $7.50 more on the 4,10. That is even after they chump you by taking vig on the amount won instead of the amount bet. The interblock machine takes vig on the amount bet on wins only. One of the reasons I prefer it. Make sure you check your local machine. They aren't all programmed the same.
