And how meaningful is this "Longest run of outs" anyway? If you calculate your maximum run of losses is likely to be 20 and you give yourself a safety net by betting a twenty-fifth of your bank - what happens when you have a run of 15 losses a win or two and another 15 losses? Your bank is still going to be caput.
When I computer model my systems against past data I record the high point of my bank and the worst following low point and work out the equivalent number of bets I lost from my peak to my trough. I have no idea how you would work this out from a percentage strike rate though.
