You can also see the sides of the board, which is a huge help. Spend as much time as they do behind a dartboard and you just need to see the general shape of the board. The rest is based on feeling and instinct.
@@blatchford11 If a pro player cant find the 20 part of a board without even looking is he really a pro. He can see both side of it so he already know where everything is. That ring keeps messing with him you can clearly see him aiming at it and when they remove the paper it's all 1/2 inch too high.
And why is that? Most F1 driver will draw any track perfectly while blindfolded. Many video games were beaten while blind folded. Experience and muscle memory is 95% of the work.
