Well, the short answer would be that at some point it becomes necessary.
Linear progression can only take you so far, and generally it only works when an individual is in a state where they are very responsive to training: beginners, coming back from a layoff, using gear. At some point you’ll realize you can’t just do 3x5 with ever increasing weights.
That ramp/backoff setup looks kind of fun, to say at least. (it also looks like you’ve have been thinking about training stuff again).
The thing that caught my attention is the way you set up the backoffs. They seem to get drastically heavier from week to week.
Say you could do a single with 100kgs on bench. Your 8RM is probably 75-80kgs. Now when you take off 10% from that you’ll end up at 67.5-72.5kgs which, if you were fresh, you could probably rep for 12-16 reps doing only five reps there sounds kind of odd. Once you get to the max triple though, it’ll be really tough.
Now a lot here depends on the way the reps are performed - of you do your 8RM with a really strong rep style for you, say touch and go, and went for either a harder rep style (so pauses, slower tempos, what not) or low rest periods you could make it more challenging. On the other hand, you could try to lift with maximal speed in order to recruit more muscle mass.
You could also vary the variaation you’re using with the top set. I’ve seem great success with clients doing stuff like
Wk 1-3 Feet up bench 8RM
Wk 4-6 CG Bench 6RM
Wk 7-9 Tng Bench 4RM
Wk 10-12 Comp Bench 2RM
After the top set they would come down 8-10% in weight and do 1-3 back off sets
On a separate day they would do “speed work” (not westside style speed work, heavier stuff, less sets. I’d call it acceleration work) with either tng bench (on weeks 4-6 and 10-12) or comp bench (on weeks 1-3 and 7-9)
My opinion is really a biased one, so let’s just get that out of the way. Personally I’ve always enjoyed working with high intensity, low-ish per session volume and a rather high frequency. Only time I could see myself doing each exercise and it’s variations on a single day would be at the end of a long diet, because that way there is less time being spent on switching from exercise to exercise and warming up. As you get fatigued you’ll also need less weight for the stuff later in the workout. If it’s isolation for thing you’ve already hit, no big deal. (Apparently studies showing that for hypertrophy there isn’t much of a difference with different frequencies when weekly volume is equal, so you could pick any split you like)
For strength, however, I feel that the higher frequency program would be superior just because strength is a skill and it has to be practiced. Sure, some people get along with only hitting lifts on one day a week, but generally it seems that doing a lift, or a variation of it more frequently brings the numbers up faster.
In the end, personal preference plays a big role
