1information about reactions to a product, a person’s performance of a task, etc. which is used as a basis for improvement.
2the modification or control of a process or system by its results or effects, for example in a biochemical pathway or behavioural response. See also negative feedback, positive feedback.
3the return of a fraction of the output signal from an amplifier, microphone, or other device to the input of the same device; sound distortion produced by this.
As defined by Oxford Advanced Learner's Dictionary, and essentially just repeated in Merriam Websters and Penguin's physical and online dictionaries. It now remains to conclude that feedback is never and likely never will be officially listed as a verb, seeing as controlling, not manipulating, a system by sheer will won't be possible anywhere but imaginary worlds, such as Aiur.
This means that when Day asked if it was fedback or feedbacked, or fedbacked, it was neither. It's a culty slang word only used in very limited contexts, and it's the duty of the members of this culture to name it.
Thus I ask you all, is it feedbacked, fedback, fedbacked or none at all?
My vote is on fedback, with thoughts on the action itself. The High Templar "feeds" the internal systems of the, say, medivac, and overloads it by its own energy. The medivac is fed a signal that then carries out an intrinsic order in the, I assume, electronic system.
