So I have been noticing this for a while, especially in long maps, whenever I look at the keys tapped thingy most of the time it's equal or close to equal.....
I mean it's just logical that a map would end up this way outside of an oddity where you'd get many small taps in one direction but only large jumps in the other. Whether it's a specific or a convert the reality that you will be going back and forth a roughly equal number of times is pretty much a given.
