Just a weighting system I'm using this season. At the start of the season I set the level which 1 point equals, and my betting throughout the season is based on this. So, I'm fairly confident of Real winning so I'm betting 4 points on it, however, if I were to take any of the other bets I mentioned, they'd maybe be 0.5, 1 or 2 points max.
Trying it out to be more disciplined and it's certainly helping, I'm 18 points in profit for the season so far, and August-October is normally a time I don't do well. It's also encouraged me to bet on single matches more, although I do still have the occasional punt on a double or treble.
