Accuracy of 1st Half Odds compared to Bookies

[trueblue2]

Alex,
How accurate are Soccer 1st Half Odds compared to Bookmaker prices. I have data from last season where Oddswizard prices are higher than Betfair, then laying the 0-0 scoreline in the 1st half made a loss of over £4000 to £100 pound stakes. Is there anything on the 1st half oddsline that is profitable ? Are the 1st half Match odds more accurate than the goals lines ? What about second half ? Or is everything more accurate over the whole match ? What is best to use Oddswizard for ? Full Match Match Odds or goal lines or 1st or 2nd half ?

Thanks

Full match odds are profitable in the major leagues as I already posted here:

Half and 2nd match odds profitablity is not stable. Depending on the league, and the season within the same league, there may be ROI 0+/-10%.
