These two stats also have stat modifiers between -6 and +6, and their default stat modifier value is 0, like for all the other stats. These two modifiers affect the move accuracy of moves in the following manner: Accuracy Modifiers: -6: 33.3% (3/9) -5: 37.5% (3/8) -4: 42.9% (3/7) -3: 50% (3/6) -2: 60% (3/5) -1: 75% (3/4) 0: 100% (3/3) +1: 133.3% (4/3) +2: 166.7% (5/3) +3: 200% (6/3) +4: 233.3% (7/3) +5: 266.6% (8/3) +6: 300% (9/3) The general formula is Accuracy Percentage = 300 / (3 - SM) % if SM is negative, and (SM + 3) * 100 / 3 % if SM is positive, where SM is the stat modifier. For the Evasion percentage, it is the same as the accuracy percentage chart, except it's in reverse, so to speak: Evasion Modifiers: -6: 300% (9/3) -5: 266.7% (8/3) -4: 233.3% (7/3) -3: 200% (6/3) -2: 166.7% (5/3) -1: 133.3% (4/3) 0: 100% (3/3) +1: 75% (3/4) +2: 60% (3/5) +3: 50% (3/6) +4: 42.9% (3/7) +5: 37.5% (3/8) +6: 33.3% (3/9) For a formula, the Evasion Percentage = (3 - SM) * 100 / 3 % if SM is negative, and 300 / (SM + 3) % if SM is positive, where SM is the stat modifier. Then, the move accuracy = (Normal Move Accuracy * User's Accuracy Percentage * Foe's Evasion Percentage) %. If this number is greater than or equal to 100%, the move will hit for certain. For a small example, if you use Stone Edge and you have a +1 Accuracy modifier (assuming the foe has a normal evasion modifier), Stone Edge will hit 80 * 133.3% * 100% = 106.67% of the time, i.e. it will always hit. Hope that sheds some light on accuracy and evasion modifiers. __________________ http://users.smogon.com/X-Act For all your Pokemon needs (and more!) including: the Defensive EVs applet, the Probabilities of Breeding IVs in Pokemon applet, and the Ratings of Pokemon Base Stats applet (now Version 2.0!).
