And the way they do that is by setting the number close to what the score will be. When they make a mistake, hammer the number and cash in.
"There is a common misconception that point spreads represent the oddsmakers' prediction of how many points the favorite will win by. That is not the case at all - their intent is NOT to evenly split the ATS result between the teams; rather, their goal is to attract equal betting action on both sides. Stated another way, they want to create a line that half the people find appealing to bet one way while the other half find it appealing to bet the other way (known as 'dividing the action')."
Pregame.com Betting Lines - How Betting Lines and Point Spreads Are Made
Power ratings are the oddsmaker's value of each team and are used as a guide to calculate a "preliminary" pointspread on an upcoming game. The power ratings are adjusted after each game a team plays. Examples of non-game factors that would require an adjustment to a team's power rating are key player injuries and player trades.
Once a game's power rating based pointspread is determined, the oddsmaker will make adjustments to that line after considering each team's most recent games played and previous games played against that opponent. Also, adjustments are made after reading each team's local newspapers to get a sense of what the coaches & players are thinking going into the game.
I don't see public perception in the line setting at all.
I don't see your point, but this is getting tedious.
The point spread is intended to divide the action into roughly half betting on one team, and half on the other. How people bet is determined by their perception of the likely outcome after factoring in the spread. If the initial spread is not evenly dividing the action (because public perception is contrary to the odds makers initial prediction) the spread is adjusted.
Do you dispute this?
