But that’s just small details, the fundamental concept is the same. I actually had the idea independently around the same time he released this article for general access. I do really like his full version with the “recovering” status, but I didn’t adopt it cause my players were already intimidated by the basic version. Didn’t want to change too many rules at once, but I would consider suggesting it for the next campaign I run for the same group of players.
