Question: Could it be the 2? I know nothing about the shoe game. But, from what I've read, KJ does a better job than most when it comes to reducing variance. Still, his swings are volatile.

In a pitch game, the 2 is of little consequence. A deficit played/surplus remaining might put a HiLo player into a bet they shouldn't make. A surplus played/deficit remaining could prevent a bet with a very strong deck composition.

IT appears to me KJ sets the standard for shoes. He knows when to get in and when to get out and has the discipline to do so. Easier said than done. He counts two tables at the same time which ultimately reduces variance and increases his position of power.
