It doesn't take 2thousand word posts to explain this. It's quite simple actually.

Shorter stacks reduce someone's edge. Everyone should know this. The smaller someone's edge is, the higher the variance.

This is true in bankroll situations. If I have a small edge (1ptbb/100), I am more likely to have big bankroll swings aka high variance.

How do shortstacks effect variance? Quite simple again.

If I am playing a donk 20bb deep, let's assume I will win 60% of the time. However, if we are 1000bb deep, I will win much closer to 100% of the time, reducing variance.

Now, this "variance" is not measured in big blinds. It is measured in buy ins. In a husng, stacks start at 75bb= more luck and higher variance.
