Rolling versus extended fasts

I'm curious of the perspective of anyone who has done consistent rolling either 48s or 72s for a long time (like weeks) with single meal refeeds. I have some analysis below, but first a couple questions: (1) Did you find, after a while, the usual difficulties on the first two days (so basically all fasted days) got easier and less like the first two days of a long fast after a long refeed? (2) Did you notice any diminished returns in fat loss or slower metabolism after prolonged rolling fasts? (3) Normally on longer fasts I am very careful with what I eat on refeed (lots of bone broth, probiotics, miso soup, pickled ginger soft entry with a meal to follow an hour or so later, meal being mostly fish and veg). Does anyone just make what they feel like/are craving for the refeed (within reason of course unless it is intentionally a cheat)? How does that go for the stomach and......let's say the other end.....issues? What I've been noticing is that there isn't a HUGE difference between three rolling 72s and a 10 day extended fast, especially if your already partially fasted. Here is what I mean. First, to go from a fully fed (so lots of eating for a few days, having reserves of sugar in muscle/organs etc) to fully fasted is about 2 days on average. For the average male, every fully fasted day uses about 0.5 lbs of fat per day. For me, on refeeds, I'm doing one meal, obviously large but not crazy and always healthy food (fish, lots of veg, etc) but not worrying about calories. My guess is I'm getting below a daily amount on this. So given before this, I'm at a fully fasted state, this meal won't be enough to completely replenish the excess sugar stores. This means, one should count on a single meal refeed in the next 72 hr fast only the first day conservatively not being fully fat adapted. That leaves about 1 lb of fat used per 72, or about 3 lbs on a 10 day period. In contrast, for a 10 day extended fast, one gets only the last 8 days (maybe 9) as fully fat adapted and that's 4 lbs. Not _too_ different on that front, however on the 72 one gets 3 refeeds to restore nutrients and some might find that smaller window easier or even better, the whole thing is just less stressful overall on the body. If longer term that method doesn't show appreciable change to metabolism, it does also offer those of us who break for social reasons to be more agile. I can't seem to think of _clear_ benefits of the extended model to this one. Especially when the extra 1 lb difference is easily made up. I've done some rolling fasts, but only 1-3 in a row before doing another extended fast. So I'm most interested in the perspectives of those that have continued rolling for a long time and how they feel plateaus and other effects went. Context: By fast, I mean a strict water, black coffee, black tea with no alterations. I use vitamin/mineral electrolytes (Multi-vitamine, B-complex, phyllium husk, vitamin D, Mag, Phos) by pill and the only "breaks" I allow are either a shot of ACV or whatever comes from the supplements.
