The weakness of the "Mongoose" progression is that you must get at 2 wins in a row, so every time you get an extended run of results without this, you're screwed. 

It happens more often than you might think, because the chance of 2 or more wins in a row is less than 25%.

It's a bit like the Stearn system or paroli up to 31. If you don't get two wins in a row, your capital is lost. But you get 11 shots at it, so chance of losing is only 1 in 15 or 6%. Otherwise a steady profit till your black day. Still the loss is expected and limited, so similar - controlled marty/paroli.
