Yeah I think people need to find the proper variation to it in terms of time. I mean think about it - if you do 5s unracks that can't possibly "hurt" you (other than maybe if you get injured by using too much weight or something) but what I mean by hurt is having a negative influence on power/strength production. For such a small time window, it's gotta have only a stim effect for the CNS (like "hey, I just got fatter by 400 lbs, how about you give me some extra power to be able to survive" kind of effect).
If you do it often (that's to be discovered, what "often" should mean for anybody) over and over and over in time, then the CNS should be able to "accept" and "consider normal" such a level of sudden electrical output in the body. It's like a depth jump basically (but obviously different in terms of signal speed and amount of time that signal is maintained) but at the other part of the spectrum.
For a depth jump and especially depth drop where you hold the landing, there is a strong signal for a short time, but you have to take into account the shock on the joints/bones etc that's going to be detrimental to health over time.
For an unrack, there is a strong but weaker signal than in a depth drop (but still stronger than what you usually get in your normal life or even strength training) that lasts longer than in a depth drop. Sure, you have to take into account spinal load over time in here as well in terms of health, that's why I said you need to be smart and patient using this.
But, again, if you make the CNS adapt and be able to generate this signal "naturally" as in "at any point in time" then it might help getting the "normal" signal threshold that occurs during lifting and jumping at a higher point than if you were not to use this "system" of high frequency unracking.
