extremity, unfortunately since /inc -uN doesn't decrease after N seconds but rather (re)initializes a timer that unsets it after those N seconds, that bit of code doesn't check precisely for "3 commands in 2 seconds". %lol.flood will equal 4 if those 4 increments are made within just under 2 seconds of each other, ie. 4 increments in just under 6 seconds in the worst case. for more info and a solution to this problem check out this post
