Thanks. I've used both of those in the past, for certain things (still do). Can't quite find what I'm looking for.
Looking for an adjustment for a system that returns a % probability to win. What subtraction to make to cover a runlne. Obviously, it will be higher for home teams than on the road (no bottom 9th maybes), and the splits can be insightful.

To show what I need, I've got the Blue Jays at 72-51, and in 1-runners 21-14. I can play around with that 21/72 wins for 29% of them being by 1-run, but I suspect that's higher on the road. I've seen those full-team listing splits and there were always some anomalies (e.g. a year the Rangers never won 1-run games, making their runline solid if you liked the side).
