Apparently I'm pleased with all of the rules but this particular one isn't at all and that's because it's a wrong choice to keep track of one's bets, loses and wins like you said bit it doesn't help you in anyway rather it boost you up to take a race with every loses you gets. I don't know for some person's but I think tracking one's losses and win will mostly lead you to some form of regrets later on.
I have already explained why this is needed. It is not so that you regret your losses, but so that you can analyze and determine why these losses happen. Maybe in a certain league you have many more losses than in others, and if you exclude this league, the number of losses will decrease. Analyzing your past matches is necessary to identify such moments that will help you avoid losses in the future. If you think that this point is useless for you, then you can simply discard it, there is no problem with that. I believe everyone will adjust this list individually for themselves.
