Notes on Matchups & Ranges

• Each category has a minimum difference required between players. The number line spans from 0 to the category’s maximum allowed difference; the shaded invalid zone marks gaps below the minimum.
• The bullseye band is centered in your range and is narrower than your range. Land the true difference inside it to earn the +100 bonus.
