There are only 3 lifts in PL. The overhead press is not a contested powerlift; ironically, it used to be an Olympic lift.
The Olympic lifts are not variations on anything.
The 'Dynamic Effort' terminology does not belong to weightlifting. All weightlifting consists of dynamic efforts.
The Olympic lifts cannot be optimally (if at all) trained by someone who is also simultaneously training the four lifts you mentioned.
I'm not sure how it happened, but there's been an increase in the number of people who think that the Olympic lifts can be trained on the side, as adjuncts to other kinds of training. Technically, it is possible, but it is also possible to train for the 400 meters and the 100 meters at the same time. It's a recipe for lack of progression in either style of lifting, injury, frustration, and horrendous form.
When did it happen that weightlifting assumed the status of an item in a salad bar of training? Weightlifting is the most challenging form of training (if you add in variables such as balance and skill) with weights that exists. The Olympic lifts cannot be accessories, because you will fail to master them unless you devote yourself to them, and doing them in a haphazard way is pointless anyway.
The ADHD of modern training philosophies continues, with people running Westside hybrid 5/3/1 neural drive mechanical drop set nonlinear ballistic periodization. If you look at Andy Bolton's program, it's maniacally simple. So is the Bulgarian style of weightlifting (which, for some reason I cannot quite fathom, has now been branded the 'John Broz method').
In your post I see capitalism plus the Internet plus an interest in strength training gone awry. Training has become like an iPod playlist jammed with 15 irreconcilable styles. Please just do one thing and get it right, and follow the existing templates. This may sound harsh to you, but it's the best possible way to get good at a strength discipline.
