I did some calculations for max bet size based on the Kelly Criterion and it seems they should be taking larger wagers for the higher % house wins. With a bankroll of 12K satoshidice should accept for the 50% bet, a max bet of 258btc. By the same token, for the 12% bet they should take a max bet of 281btc, not 120. Either they are taking bet sizes WAY to big for their bankroll, or they are not maximizing earnings by accepting higher limits for their other wagers.
To calculate this I used an excel function set I used for sportsbetting that I downloaded from here:
The function is SBKELLY(win%,usodds ie -110, kelly size where 1 is max and 0.5 is half). In order for the function to work I had to convert some things from the satoshi website. Basically I was required to invert the players odds and frame it as a bet for the house at odds that paid out greater than the losses. In advantage gambling one seeks to maximize earnings while minimizing the risk of ruin so the Kelly Criterion is implemented. But this is as far as my understanding of it goes as I am merely a monkey with a spreadsheet.
