Precision will be the measure of how accurate something is. Well, we disagree about how the word should be used - but that's not suprising. It is an accurate but imprecise description of the physical phenomena. It's whatever registers the results, registers a measurement. Since all measurement systems which are used as tools by physicists are themselves quantum objects, it can easily be shown that they too are part of the quantum system as a whole and that that system itself only takes on a particular history when observed.
Minds are both their causal powers, their thoughts and their perceptions.
Human bodies are physical systems governed by quantum laws which also take their actual history only in response to observation. A single statement is not a deduction. That the Blah, blah, blah. Once again, retreating to some pre-rational unwillingness to accept the evidence of as presented by physical scientists throughout the world since the turn of the century seems to be what you are doing. I am merely repeating their finding and do not wish to repeat them as a whole since it would be outside of the focus of this discussion group.
