WinPicks for college football uses a different prediction engine that is based on conference strengths and average margin of victory. This method works well for college football. Tracking all of the game stats for 119 teams would require a lot of data to be downloaded and processed each week, and statistics compiled against inferior competition are not that meaningful. For example, the top offensive teams in the country often pile up a lot of their yards against weak non-conference opponents.
The "Lower Betting Window Limit" and "Upper Betting Window Limit" are the two parameters that set the size of the betting window in a prediction formula and determine how many picks WinPicks will recommend. The betting window refers to the difference between predictions made by WinPicks, and the actual betting line. For example, if the betting window is set to 1 to 7 points, WinPicks recommends picks when the actual line differs from the WinPicks line by 1 to 7 points. The lower and upper bounds of the betting window are set using the parameters named "Lower Betting Window Limit" and "Upper Betting Window Limit". The default betting window is 1 to 10 points. If you increase the window, WinPicks recommends more picks. If you decrease the window, WinPicks recommends fewer picks.
