well in our house i would be under what some of you ,may call tpe or 24/7, even when my owner isnt home,

but i would also argue that total power exchange by deffinition cannot be accomplished it is in fact not possible, 100%, for that would require an automoton a machine, not a human being,(tell that to the server lol)

honestly the submissive allways has a choice to resist,and unless metally crippeled with a brain injury or some other mental condition; the free will to choose

the ammount and or type of resistence tolerated is dependent upon both the sub and the dom, with some its more give and take, with others its more push and pull, but in all the sub must choose to submit or resist just as the dom also must choose to be strong or yield

so every exchange is a total power exchange in a way, its just a matter of extremities along the golden mean acording to aristotle
too far one way, a weak and or emasculated dom with the subs in charge like roll reversal ,,,, to far the other way and we find a dom by themselves with a crushed or broken sub

i hope this helps you define where you find yourself in the realm of power exchange
