Shouldn't need to be said, but this is really the kind of thing you're going to have to play around with and figure out on your own. Is it realistic to think there would be one right answer to this question, or even that the question makes sense as asked?
There are no magic percentages, set/rep schemes, frequencies, periodization models, etc... The "resources" you've likely consulted should just be used to get you in the right ballpark to start. From there you need to adjust; that applies irrespective of training philosophy.
I don't know if you're read the 3DMJ Pyramid books, but that's a good resource to get a handle on training for powerlifting using DUP principles. You will see there that there are many ways to set up a training cycle using these principles.
Just to give you something of substance, my wife's training is set up using DUP principles, and her power work is very close percentage-wise to her strength work. The reps are lower. That same setup has not been sustainable for me, though, hence the need to try different things.
