AZ / NO, line advantage quick question...

AZ / NO, line advantage quick question... I'm arguing with a friend, but I cannot find a prior post that discusses this...we've been thru this before, so I apologize... the WA line is AZ +7 vs. NO, and say that's where it closes. But if you can get AZ +7.5, what pecentage AP does that become? thanks!

assuming the 7 falls 6% of the time, and 7 is the "fair" line, this makes the play a 53% play, giving you about 1.25% advantage at -110.
