What you’re describing is exactly what I’m already doing. I’m averaging a bit over 2 lbs of fat loss per week, which is about the upper cap on what’s healthy. One note I’ve discovered is that Rolling 72s are actually a lot easier for me than Rolling 48s. It’s always the first day post-feeding that’s the hardest, so my recommendation would be to aim higher, rather than lower, and keep as consistent as you can. Aim for a month at least, and then review.
One thing I like to do is go out to an AYCE restaurant on my feeding day. Just make sure to eat a bagel or something a few hours in advance of your large meal on feeding day, and maybe some fruit a few hours after the fact, to avoid food comas where possible.
What I mean to say is what you’re suggesting is very viable, and works well for me. Of course, your mileage may vary, and always listen to your body if it tells you something is wrong :)
