I'm not sure I can agree that the answer to the question I posed is 'Yes', unless we are looking at it in very different ways. The large majority of NFL results don't fall particularly close to the result 'predicted' by the spread, certainly not close enough that getting half a point here or even two points there will make any difference to the result of a wager.
Teasing is interesting of course, though you have to hit two or more games to win a teaser. But how is it indicative of the accuracy of the market to say, essentially, that if you add six points then it's really accurate.
I'm not sure I'm disagreeing with you as I probably don't know what you are seeking to achieve with these numbers, but it seems to me that a market whose 'predictions' are significantly wrong for a large majority of games can't be all that accurate.
