Go to any armor in the pedia, press the info button and look at the energy recovery / stun recovery / morale formulas
What is readiness?
Baby don't hurt me,
Don't hurt me
No more.
...Ah, so the question is about definition 'what the bonus is'... IMHO, 'bonus' is something which gives us
extra points of anything. Ok, let's open that menu then, sacred and unknown to me... What we can see there? Is there something beyond the
normal, something we can count as
bonus? I think not. Since we have readiness as a basic stat now, the basic counters formulas contain it. It is
normal now. Not
extra. We can regenerate with full readiness faster, than with a half of it? Hmm, maybe we should speak about HP then? Full HP provides us
extra chances to survive, than half HP?
Oh, man.....
I can give counter-direction. Go to 'commendations' menu. There you'll see all the bonuses your soldier has.
