Wow, you are big punter indeed.
40% commission discount means that your points are +-50,000.
The maximum I had was 15,000.

And that was one year ago. When I was in the run of winning anything I bet on for 2 weeks in the russian league.
I don't bet regularly, just for fun, love the thrill, and I don't really care about the betfair holiday to stop points decaying.

I think their soccer odds are the best. Not sure about horse racing, I don't understand animals. What I understand well are girls and the financial market.
The only bookie who can match their soccer odds is sbobet.com, but still, betfair still win by big margin. esp. if you are going against all odds, ie. betting for the seemly impossible, such as 3-3, 3-2.

I think, that you as a big punter, know that those kind of things do happen, and I love noticing that kind of possibilities. I love it when people underestimate the possibilities of that happening.
It's like tonight game, benfica chelsea, I'm going for over 3.5 and 3-2 or 2-3.
IMO, the odds for heaps of goals are underestimated, for that game.
