>100% accuracy may occur when a single projectile hits two different players, though I have not tested this. It could also just be a miscalculation.

Pretty sure 100% accuracy occurs when you get guns like the shotgun which fire multiple projectiles. Having one projectile hit should result in 100%, while having multiple would make the accuracy even higher.

This could also very well be the case based on my limited knowledge of the calculation.
