I know it affects Efficiency, but its value ranges from 10 to 25 (I think I've even seen 5, but never more than 25), so how does that number translate into the actual reduction of Efficiency?
For example, a strategic bomber with a Shock value of 25 is supposed to reduce Efficiency more than one with a Shock value of 20, but is that difference actually noticeable in-game?
Thanks in advance for any clarification
