Thanks for giving us some more rules. These are as funny as the rest.
According to you, the chance of the horse that has performed on the course has increased. Increased from what? When you assessed it's chance (which we all know you don't do), you would have already known its performance on the track.
And I like it that the chances of the other horses have decreased - including those that have never raced on the track. Keep up with the generalisations, you're the king of them and that makes you the king of losers. Well done.
Suddenly, when you bet, you add extra because of something like this. It's hilarious. Of course the readers know you don't actually do what you claim, since it's all just one big fairytale - isn't it loser?
No wonder when given the chance to put up either selections pre race or even back that up with an assessed price - you can't do it and you run for the hills You're a fraud. And you've exposed yourself on here for all to see it.
