The Regional Offset Margin defines the relationship between one group and another based on the hypothetical goal/point difference if the best team in one group played the best team in another group. This offset is then subtracted from the local power rating of each team in that group to generate the national rating of that team. As an example, the list below contains high school boys' lacrosse groups along with the offset margins and the best team for each group.

Hypothetically, if Huntington (NY Section 11) played Dulaney (MD 1/2/3/4) on a neutral field, Huntington would defeat Dulaney by 3.00 - 0.24 = 2.76 (about three goals).

Regional offset margins are evaluated subjectively and are based on games between teams in different states. The state ranking of each team within its state is taken into account. The more games, the greater the opportunity to develop the ROMS. Since states typically play in neighboring states, information tends to propagate from one state to another even though there are no games between some states.
