What I find bizarre is your interpretation of this line form the
documentation:
to avoid statistical bias Round alternates between going up and down
halfway between integers.
Round[Range[10]+.5]
{2,2,4,4,6,6,8,8,10,10}T
Of course every time run this, you will get the same answer.
SO could you please send us an example where Round, in your own
words: "doesn't give the same answer every time"?

I think the problem is just the opposite: some engineers are just
not "Mathematica grade" mathematicians and programmers.
