I am one of those like you Craig.... I scratch my head sometimes and wonder how. Having said that, I think I can predict what response you are about to get.
Those who can, will refer to thousands of ranked rounds, spanning many years and will say "Practice, practice, practice"
Those who can't will ask the same question at best and come up with all kinds of daft conspiracy theories at worst.
It's the way it is and for those who can.... I take my hat off to you. I hope that maybe one day, I might be one who can as well !
