I agree about 3 paragraphs into it... then it gets a little dicey. How are you going to use enough weight to stimulate muscle growth when your RI is a mere 20 seconds? As you shorten RI, intensity is forced to drop, not by choice, not by will, and not by some magical theory.
And also, your volume is ridiciulously high and non-specific. 8-20 sets? Don't you think that is a bit broad?
You can work on power, you can work on strength, and you can work on muscular endurance... BUT, you cannot work on them ALL at ONCE.
Can you incorporate what you've just stated into a routine? Sure, but to work on power, you need less intensity and more speed. To work on strength you need a moderate rep range, and an intense weight, and a reasonable period of rest. Try deadlifting 90% of your 1RM with 20 second intervals, its impossible... the weight will be forced to drop because you have not recovered suffeciently and because of basic physics.
That's bullshit. If you deadlift 300/5x5 with a RI of 60s (1RM around 365), there is NO way your body is physically capable of moving the same amount of weight quicker (IE: with a 20s RI). Something else has to change, and that something is the intensity. So sure, you can have 20s RI's but your not going to be moving as much weight, you'll be moving it faster, but you won't be able to move nearly as much weight.if you lift as much as you can for 5-8 reps and rest 2-3 minutes between sets, you will be able to generate a lot more force (i.e., lift heavier weights). But over the course of many sets, your average work rate will be less because of the slower pace. Your muscles will still grow, but not as quickly as they could.
What your describing is density training... it has it's place, but you can't beat the laws of physics.
