Heat Buster

When using heat buster, I find I occasionally end up being pushed back(only once until I reset the tower however). I'm not quite show how exactly it works, since it doesn't always push you back, and if it does, you don't always move back the full distance. Anyone care to look into this for me?

I haven't ever been pushed back when using a tower cylinder under normal conditions. If there's latency though then it might move me to where the server says I am.
