Thanks PipZombie. Yeah I know how to work it out, it's just Mark isn't doing this at all with his results. His risk per trade doesn't change for 2 years, doesn't factor in the account growing. His stake at Jan 09 is $10 per pip, which means a risk of $400 per trade = a starting account of $20k. As far as I can see his stake never changes throughout the 2 years, so it has nothing to do with 2% MM. I ran a test using an arbitary starting account, and during those 2 years, using 2% MM, your account would approximately triple, not increase by a factor of about 37 as in Mark's table! It's misleading at best.
