Worth noting that this field is reaching diminishing returns due to analyses. You might be 2% better than a stock analysis, but that's usually not a sufficient edge to exploit profitably unless you're talking HUGE numbers.

Finding a problem someone has, solving it with analysis, and offering to license/sell it to them (once it's proven to work) is probably more lucrative.

Unless you're chasing the variable rewards skinner box. In that case, I'd probably just take up a cocaine habit -- it'll be cheaper.

Late response, but figured I'd mention that we have new variables now that we didn't always. Pitch FX, fielder location, etc. Not that it makes a huge different, but playing daily and averaging out over time, it can really affect matchups (again, over a large enough sample size).
