Mike, I went through the same inquiry of Bib’s old posts years ago. I finally found definitive answers in these two threads.

Is two days off in a row preferable?
I am adjusting my hanging efforts accordingly.
Basically Bib was a family man, who didn’t want his hanging to leak into his family life on weekends. I think he was actually stealthing it for his kids but not to his wife. Ironic that he eventually ended up having a family PE product business with his sons. Anyway, with what sounds like a few kids growing up, you can imagine how much free time he had on weekends, not much. So he would sneak in a couple sets here and there, but by comparison to his weekdays, the weekends were effectively off days. Weekdays he would average something like 6-7 hours in the hanger if memory serves me. Weekends he would average maybe 30 minutes in the hanger, and some weekends be completely off. I don’t have a link, but I remember him posting that getting a set in within 36 hours of the last set insured some of the fatigue would carry over through the weekend. Whereas without this refresher set, deeper healing would begin over the weekend.
Furthermore, the above two links shed some serious light on what Bib really thought about the ideal gaining program, opposed to his most common advice to new hangers. Presumably he doesn’t believe most new hangers have the framework of understanding of IPR principles to implement the ideal strategy he describes in these two threads. And I think he might be right about that. Anyway, he says that if his schedule were not constrained by family life, he would have hung until reaching "total" fatigue - I assume you know what he means by that term - and then taken rest time to let things heal up completely before beginning another fatigue cycle, going to total fatigue again. This information proved to be a golden ticket for my own hanging, and I was able to consistently get length gains from using Bib’s ideal hanging program as described back in 2002-2004 when it was all still fresh to him as opposed to many years later when he starting telling everybody to hang with zero rest days.
I understand why he tells people to hang as much as possible. It’s because he knows 90% of guys or more never even get past 10 hours per week, and his ideal style is predicated on guys being able to put in at least 20 hours per week to reach total fatigue in the first place.
Of note, and something I also neglected to add to Vanquish’s recent thread - Bib mentions that hanging near total fatigue is also hanging near injury. Something I observed as well in my own hanging. The target tissues are extremely fatigued and worn out, so it is both a time of gains, and a time of caution. Personally I would end my cycles both because I would get sick of hanging so much time, and also partly because of safety reasons.
Hopefully this tidbit of info unlocks some serious gains for you guys.
