I archived all my data pre 2014 and took lazy to write a script to look at it, but I checked every game since 2014.
Some nice standouts:
Cin @ Home: 114-307-0 (27.08%) 65.71u
Col @Home: 138-290-0 (32.24%) 38.58u (this one seems like a no brainer, but it must be the home teams don't bat b9 if winning thing)
Det @ Away: 96-329 (22.59%) -48.3u (ouch)
Mia @Away: 89-340 (20.75%) -59.26u (only down 59 units?)
SDN @Home: 104-318-0 (24.64%) 30.26u (low scoring park + bad team + home is profitable?) yet Away: 85-347 (19.68%) -64.49u
SLN @Away: 144-285 (33.57%) 57.13u
and the best one
Can you guess which team?
Away: 91-339 (21.16%) -91.78u
Only two teams are positive in Home and Away over this span. Can you guess?
The total home/away since then:
Total Home:
3439-8944 -37.31u
Total Away:
3292-9213 -285.51u
Not looking too good.
