I have a problem with my spread model NFL I can't fix. Lets say a team has a negative home field advantage (HFA) and it's proven that divisional games in NFL result in a +-50% lesser HFA...how do you handle that?
1. A negative HFA of -1.0 results in -1.5 (according to HFA gets less); or
2. A negative HFA of -1.0 results in -0.50 (according to divisional games tends to be closer).
Which one and why? Anyone?
