I don't think you need to over complicate it. Part of the beauty of it is how much you can adapt it. So, if it's your second or third day in a row training, you're not exactly going to be feeling fresh. Just hit the minimum reps and move on. You'll still make progress, and you'll feel that significantly when you get to hit that day feeling fresh and can go all out. In other words, if your recovery is already compromised, don't go 100%.KPj
Point taken, hit the minimum when you have to, but take my opportunities when I'm feeling fresh. Looking at my log, I feel I have been doing this - but this is good advice.
I think it's prudent to take an actual deload week once in a while, if not every cycle, maybe every second one. A heavy 5-3-1 workout (wave 3) has a systemic toll on the body, and a wave 3 workout every week, even with different exercises may cause issues in your recovery at some point. The deload is not just for muscle recovery, it's the total body that needs the break. Just a thought.
Another good point, and probably more important. As I develop through this program, my CNS will need a break as much as my muscles (if not more, as my muscles my more readily adapt?!). I was concerned about having 4 workouts of "wave 3" intensity close to each other (within 5 days, depending on my availability), but I guess I would also be gaining a fair chunk of deload following this.
So far, I'm leaning towards:
a) Continuing as I am - taking the good sessions, with the bad (or rather 'minimum sessions')
b) Be prepared to have a break for 1-2 weeks if required, maybe early next year
