I do understand why you choose betfair! Spread + commission is less than going in to the bookies. Why do you play these games on betfair when there is live games on biased roulette wheels taking place for over 16 hours per day in the UK? Betfairs atomic selector coupled with the von neumann whitening corrector is random. I know this is fact as I have checked! I have checked static, positional, differential positional and integral positional on a number of games and they are all random and not predictable.
