Oh come on with this drivel. First of all what is even meant by the labeling on the Y-axis and how do you even come up with a measurement to give a reliable statistic? Mods shouldn't tolerate this on this subreddit. A line has to be drawn somewhere because this is like the fiftieth time I've seen somebody post this. Maybe get it over to /r/lordoflight where it belongs.
