The missing component in every RL database I've ever seen is breaking down the actual record for a team at -1.5 and +1.5 respectively.
"RL records" are a mixture of a team's record vs "the spread", but both Fave roles (-1.5) and Dog Roles (+1.5) are crunched together.
So if you're wanting to know only how a team does if graded at +1.5 or -1.5, you have to do the work manually.
