In his opinion, it needs a revamp and he believes that the PDC should look to the likes of golf and tennis for inspiration. Mardle also added that he thinks a points system could be the way to go as opposed to the current money rankings. "The ranking system is poor, it really is," said Mardle to . "Basically, if someone wins £100,000 23 months ago and you win £100,000 yesterday, they both count the same. Within that 23 months, that person may have given up darts, but it still counts the same.'' "It needs to kind of disintegrate month-in, month-out, a percentage. I don't like pounds anyway, if it carried points it would be easier to work out.'' "I remember Robert Thornton winning the Grand Prix, when he had to defend it he went to bed the world number seven and woke up the world number 16. No one becomes that poor overnight. "Beating Michael van Gerwen should carry a certain amount of clout. Is there a perfect ranking system? No, probably not. Is there a better one? Yes. "The PDC have got to look at what other sports do, Golf and Tennis both do a points system and a money system, so why can't darts do that?"
