I am not sure what you mean. If one is not creating a proper line or total then they obviously need to address that or stop betting the games until they solve it. Agree there.
But there really isn't anything to adapt to from a betting perspective other than perhaps not value betting as much. The volatility makes the value of a half point a little bit less than in prior years. The higher the lined total, the less value each half pt in the lined spread is worth. In any event for those of us that create our own line and number ... unless there is an error to how you are approaching it there isn't much to adapt to other than maybe increasing variance needed to invest, since the value of each half pt has decreased.
