In recent months I've transitioned the majority of my investments to Money Line (ML) wagers only. For me, it's much easier to quantify a potential edge (+EV) with the approach I'm using. However, this is a somewhat short term "experiment" and I haven't compiled enough data as to the limits for favorites. I'm using my quantifiable edge (or at least I hope so...lol) against the line along with Kelly Criterion to determine the wager amount. Though I would like to believe there are no limits in regards to value, I do remember reading years ago, like back in the 90's that it's just not going to happen with -220 favorites and beyond (Source: unidentifiable book on betting baseball: Gamblers Book Club Las Vegas). Or is value as it seems, value?
