Your figures are pretty much what I work to, and despite what some people may believe, it is inevitable that one will encounter runs of outs to match those figures... if my punting experience is anything to go by. Almost all of my various plans have run to their maximum expected run of outs at least once.

Stebbo correctly points out that once that maximum expected run of outs has been met and ended, there is absolutely nothing to stop the same run repeating itself immediately after the previous drought-breaking winner.

Runs of ouits is one of the prime reasons, I believe, why no amount of posting of succesful methods on this forum will ever dent prices on offer for any significant period of time.
