RFCSPACE If you assume home games we're usually favourites at around 6/4 -> 18 games so far and away we're usually underdogs at around 9/4 -> 16 games so far.
10 home wins would yield £5 profit per game -> £50 -> less the 8 games we haven't won (-£80) would be a loss of £30.
9 away wins would yield £12.50 profit per game -> £112.50 -> less the 7 games we haven't won (-£70) would be a profit of £42.50.
So overall you'll be looking at a whopping £12.50 profit for your £340 investment.
Very rough I know, but betting on everything doesn't really work. The law of averages would imply you'd break even over time.
errrrm, £10 @ 6/4 will give you £15 profit, 9/4 £22.50
time well spent though
