Thanks for that link Crash, there's nothing better than to see some buggar use a pageful of numbers and letters (dissapointed with the lack of greek letters) to prove what you felt was the case all along (even if one's comprehension pulls up short after the introductory paragraph).

If you are winning on level stakes though there must be something to be said for increasing your bets (safely) as your bank gets bigger. Obviously your percentage return won't improve but your bottom line must.
