I don't even have price boost anymore

That thing you are doing in your thread is a pretty good showcase of what is possible and why it's of utmost importance to shop for odds for any ambitious betting person. But then again, no offense, it's pretty pointless, if you are comparing odds from bookies with average odds. You can get way better odds with other books than the ones you are using/comparing. This is like comparing your VW to a Smart, when there is Ferraris out there you could drive.

Do you have any (more understandable) P/L for your bets ? Any yield/ROI ? Just getting higher odds in one book compared to other books doesn't mean these odds carry any value no matter what.

As a successful punter, you will always run into trouble with limits and all those things. There is only few books out there, that are welcoming winning players. And thats just because they follow their bets and get valuable information for rather few money.
