I am a big fan of the half-point calculator, but it appears that the outputs haven't changed in the last 10 or so years, and most sports definitely have changed. A friend of mine that is very good with analytics thinks the 3 in the NFL is only worth ~18c now, but I still think it's worth ~24c, and the SBR tool has it at 25c. Seems to me if the dataset being used isn't using from the past ~5 years or so, it's going to be less accurate. Anyone have the details on this? I've looked around a fair mount and can't find anything on it.
