Kickboard takes all of the mastery scores you enter on Scorecards and turns each one into a percentage. Then Kickboard takes an average of all percentages (essentially, Kickboard adds up all percentages and divides by the number of scores). The more times a skill is assessed, the higher influence it has on the overall grade, because the skill has more mastery scores that contribute to the average.
