How often do the odds makers "get it right"?

books are more casual about their opening lines than you might expect, because they know the market will bang them into place before the limits get high.

My first oddsmaking assignment:

BOSS: Why don't you make some matchups for the Senior PGA tournament next week?

ME: I know absolutely nothing about golf. I can not name two current Senior PGA golfers.

BOSS: Don't worry about it. We've got some stats you can look at.

ME: (peeing my pants)

BOSS: (trying to comfort me) Look, we'll only take a nickel, use a 30-cent line, and move it aggressively.

(translation: we'll set the max bet at "only" $500, we'll make the favorite 30 cents higher than the dog--ie, -140/+110--and we'll move the line at least 25 cents every time a sharpie bets at it, which should quickly "bang them into place before the limits get high".)
