I love this tool, it's very useful for several tasks!
One of the biggest problems that I have with it is that it's really bad at detecting pauses. It shows when a pause starts correctly, but the end of the pause is always wrong by some random amount of ticks (usually it's in the 3000-5000 range). If a pause happens during humiliation it might not even detect there being a pause at all, it'll just think that the humiliation lasts a really long, and still incorrect, amount of time.
I also find it weird that it only shows who died from an airshot (these are pretty much the only useful events in the event log) and not who got the kill.
If these two issues were fixed and it also had a way to record killstreaks it would basically be perfect!
