I&#x27;m on the west coast and I&#x27;m an expert (Ph.D + Ivy postdoc) in mathematics.  I&#x27;ve played a little bit recently and my feeling is that the low hanging fruit has been largely harvested - Large variations and playing against mostly experts means it&#x27;s very hard to beat the 10% rake, without doing a lot of time-consuming tweaking.     I&#x27;m more interested in doing this for the challenge and to test some data science tools in a tangible way (Kaggle gives a different kind of feedback)<p>mwfd541 at gmail
