93% of top scores..
that
could be a ~1250 FITA (congrats), or a less impressive ~550 Portsmouth. what sort of rounds are you using to reach this number?
law of diminishing returns is in play; its probably more than twice as hard to shoot a 590 FITA18 than an 570, so the people at the top spend many times more effort and practice/gym hours to get the extra 20 points that represent the enormous chasm of skill that seperates them from us riff-raff.
i dont do a strict routine of visualisation, but rather just daydream about nice shots in lectures and such, so my visualisation is "little and often".
i used to watch some videos of the good archers shooting every now & then; how to shoot slowly infiltrates into your head that way.
1 hour with a
good coach, can help far more than many weeks of regular shooting. however good coaches are so rare as to be practically impossible to find, and having a coach in this country is just a lottery. (in that you will almost certainly lose, but the gain can be enormous if you are lucky enough to find Graham Williams)
being super-strong also makes things alot easier. week-in-week-out technique consistency can be constantly perturbed by your body just wanting to fold up and keel over because you have a pair of 50# Samick extremes that were mistakenly marked 44#. thanks Samick.
lots of good advice from others

. make every shot count, which is especially easy if its only in your head!!
