Gvido and Wrongly -

Not to speak for mikemd, but I think he's saying what he'll take for odds, not what he'll give. It's based on the odds he would require to expect to get 100% of his money back over the long haul. A track line would build in the takeout, so the expected return would be roughly 85%. Based on what I think he's doing (which is in principle what I do, but I require a 125% return when I make my odds line), mikemd's line foots perfectly.
