I was quite sure that he will reach a new step of recovery when he reached a certain amount of unit exposure, but he recently posted that he finished a singular session with a maximum exposition of 203 units whilst the game ended at the first step of recovery. If we compare it to the session that he posted with more details, he finished the game in the third step of recovery with just a maximum exposition of 182 units.

So it seems like he changes recovery steps after he reaches a certain amount of numbers played in total, which is quite odd.
