It is hard to answer that. As a player in Dave's original campaign, I only saw my character card (a 3x5 index card) with my characters stats and description a handful of times over a period of over 4 years of playing almost every weekend. So, we did not have a lot of visibility into how these things actually worked. Dave talked about these things, but we didn't see how the actual mechanics worked. None of the rules were published or in print while we were playing in those days. They were all in his notebook.
