What the addon does is deduct your ping from the remaining duration when the acknowledgement is received.

This is something the game should already do, the addon would not exist if SE fixed this issue with animation locks. The tool still doesn't let you weave oGCDs faster than a 0 ping environment would, it simply makes the game's animation lock behave as if you were playing with 0 ping.
... You can set it to go below 0 ping equivalence. This is one of the things that the pvp bots were doing.
