20/20 vision, also known as Visual Acuity, is acuteness or clearness of vision, especially form vision, which is dependent on the sharpness of the retinal focus within the eye and the sensitivity of the interpretative faculty of the brain.
In this Terminator Tournament you will have to make sure you have 20/20 vision to have the best chance of winning, as the aim is to gain the best points difference total.
For example, Player 1 might gain 121 point and lose 100 over the tournament, giving them a total of +21 points. But Player 2 may gain only 80 points and lose 50 giving them a total of +30 points. In that case, even though Player 1 gained more points, Player 2 comes off better and would therefore win.
There is only one requirement to join this tournament... you must NOT be an "Officer" (score must be below 1600!). There is an identical tournament for "Officers". (Players with a score of 1600 or above.)
