Strategic Deconditioning

I'm currently following a HST routine using the following parameters:

2 weeks: 12 reps (2 sets each of 10 exercises every other day, cardio and body weight exercises during non-lifting days)
2 weeks: 9 reps
2 weeks: 6 reps
2 weeks: 6 rep max for each lifting session alternated with negatives.

HST recommends a 9-14 day strategic deconditioning period after the first 8 weeks. I don't feel that I'm overtraining or feel that worn down, will skipping this period and starting with 12 rep sets after a day or two of rest be beneficial for hypertrophy? I think it wouldn't be a terrible thing to get a start on cutting by doing cardio/body weight every day for 9 days or so, but I also feel like it might be sort of defeating the purpose since I'm going to be doing at least another 8 week cycle before I start cutting in earnest, and to that end, I'd like to build as much muscle as possible beforehand.

Thoughts?

I dunno, I didn't find the six weeks I've been in the program to be all that challenging. It could be because I've made some gains and the "maxes" I picked weren't really 100% of my 6, 9, and 12 RMs. I also had a 3 month involuntary break before I started the program because of a wrist problem, so I feel that I'm pretty fresh. I think I might just do one calendar week of SD if I end up being tired, we'll see though. I started my 12RMs with low/moderate weight (185 on bench, 225 on squat, 155 on deadlift, for example) and you move up 5-10 lb per lifting day within the 3 month period, then start at a bit higher weight when you drop reps. I think I'm going to take a week off, then start the 12RM period with 40 lb more than the last cycle, then see where I stand by the end of the two weeks. If it's pretty hard, I'll drop down 30 lb or so to start the 8 rep period (which means I'll end about 30 lb more on 8RM than 12 RM) and if it's easy I'll just repeat the 12RM max as the starting point of the 8RM (which means I'll end 60 lb heavier) and same for 6RMs. This last cycle I dropped 30 lb from each, meaning I was @ 225 12RM, 255 8RM, 285 6RM, which was pretty damn easy, and I don't think it represents my real maxes in each of those categories. 40lb more should put me in the ballpark, most likely. I've typically been doing 2 mi of HIIT for my cardio, on off days, with increasing speed, which I think I will continue.

I do HIIT on a 400m track at a campus near my house usually. I'll just sprint 400m, then walk 400m, repeating the process 3 times for a total of 2 total miles of distance. It doesn't take too long, by now I'm down to a bit over 20 minutes for the whole thing. I'm not going to do HIIT during the SD period, probably just walking on an incline treadmill and light body weight exercises to make sure I actually decondition hehe

Yeah, like I said in the post above this one, I'm not doing to do HIIT during the SD, instead I'm just going to do incline treadmill.
