It’s hard to say because everyone experiences recon in different ways. With that said, you’ve not just pushed but surpassed the limits farther than anyone I’ve seen on this forum (against everyone’s recommendations), so it’s hard for anyone other than Saint and Fire to really draw from their own experience to answer you.
At the end of the day, you’re the only person trying to listen to 8 ZP titles so you’re the one who will be discovering the answers for the rest of us. I do think you’re just going to subject yourself to more recon, I can say that I did not listen to Qv2 instructions but I would run 2 titles at 4 loops a day, maybe 6 max, with 2 rest days a week. With ZP, I listened to a 2nd loop by accident and it gave me worse recon than anything I experienced with Qv2.
Yeah, you should think about doing that 15 day washout now before starting a different stack IMO.
