As an alternative william hill offer the option to display the odds decimally rather than fractionally, so 4/1 would display as 5.00 i.e. bet a pound returns £5 (your winnings plus your stake), incidentally they also have better odds for spencer 5/1 or 6.00, so betting a pound returns £6
now me, I put a tenner each way on Alex in the first week when he was 50-1 to win (they've stopped taking each way/place bets now), that's a bet of £10 that he gets into the final three at 10-1, and a bet of £10 that he wins at 50-1, so if he finishes second or third, I'll pick up £110, if he finishes first, I'll get £620 back.
