no, not completely mechanical. There is a guy over at the fox that did this mechanical starting back in 2003 and then tweaked it each year. I pulled off his method. I lost all my bankroll in 2 series in september with this method back in 2007 and started tweaking it more, not playing into september, not playing at the start of the year, if at all possible not playing interleague and not doing martingale but labouchere. Do a google of labouchere for a complete explanation. But instead of doubling up each time which can get quite chalky (ie- game 3's of say yankees at home) using labouchere you can still protect your bankroll and still recoup your losses by spreading them out.
