It is like everything else in this world, some people are better than others at certain tasks.Take a pro snooker player for example, most of us could never in our wildest dreams imagine playing to 10% of their standard same goes for pro darts players, hitting 180s,140s for fun.
If the cynics check the top players stats and see the amount of ranked rounds they have racked up and realise the amount of time it takes to play these games it is believable that they can shoot in the low to mid 50s consistently. Maybe they are simply better than us and not cheats.
Enjoy the game guys and maybe just accept that we all can't be the best of the best.
