I wish I could tell you, you will hit X with it, but the work will be up to you and how your body responds. I did the following, for my deadlift, (I never used it for a squat, as I am not built as much to squat as I am to deadlift) about 6 years ago, I did this w/o, which was based on Smolov and written by a German oly lifter on a site I frequented.
He originally wrote it for 4 days per week, (MWFS) but I dragged it out, to only do 3 (MWF-at first) a week, then dropped to 2 (M-F) with some deload or speed work between/ wed. the days. It was just getting to hard for me to pull with that much volume along with intensity. Mind you I was also working 40 hrs a week at my job on my feet and not always light work necessarily. I did a pre W/O short cycle to get a pretty true 1RM...
Week 1 M-70%x9x3sets W-75%x7x4sets F-80%x5x5sets (not a bad week)
Week 2 M-85%x3x6sets W-75%x9x3sets F-80%x7x4sets (getting tougher)
Week 3 M-85%x5x5 W-90%x3x6 F-50% speed dayx3x8sets (tough)
Week 4 M-77.5%x9x3sets W-82.5%x7x4sets F-50% speed dayx3x8sets(by now I hated the higher reps)
Week 5 M-87.5%x5x5 W-50% speed dayx3x8 F-92.5%x3x6sets (tougher yet)
Week 6 M-50% speed x3x8sets W-40%- 50% squats onlyx3x6sets F-PR pulled #600, then #575 then #505x5 (woo hoo week)
I will say after the 2nd/3rd week, (I had 6-8 heavy w/o's in)and it started to get a bit tough and it did beat me up some. When I went to bed at night, it felt good to lay down and my low back felt very trained and almost heavy with a dull all over ache.
I think I gained about #30 on my pull maybe, but my dead was near #580 at the time and I wanted something to push me up over the #600+ mark. All drug free, some creatine, erase I think, BCAA's.
Now, I think the supercompensation took place but I think I rushed it too. I think I was stronger doing some rack work and partials below the knees a month or so later. #615-#630 and I think I did #580-#600 from 2" def.
Thinking back, I am glad I tried it. If anything it builds work ethic. I think I have made progress like this without beating myself up so much and do agree that you don't need to get this greasy IMO. Maybe I would drag it out over 1-2x per week and a longer cycle. 9-12 weeks
I know squatting is a bit different animal than deads, so again YMMV. All the best and have fun most of all.
