For example, if power numbers indicate a line should be 3 points different than the market, you can’t ignore everyone else and hang a 6 when the world’s at a 3. Instead, the objective is to shade the price just enough (say 3, -125 in football) realizing that any sharp bettor who shares the same power numbers or thought process on a game as you will be discouraged from betting the “correct side” at your shop.
