You also have to take in mind other factors that effect suppression such as the loss of a nearby buddy who is in LOS especially if its armour. You cant predict whats going to happen occasionaly you get an odd result like everything else in the game but you can guess how he is likely to react.
With suppresion you do this all the time prep firing enough stuff to in your judgement to suppress the enemy before making a move for example & then having to deal with the guy that didnt conform & is still dangerous.If there wasnt an ellement of randomness you could predict the effects way to easily.
In my opinion the game works very well till units get to the experience 100 mark when they shrug off suppression with ease & become predictable supermen.
You learn the does n donts pretty quick, fighting in a freindly armour graveyard for instance is a really bad idea while having a platoon of elite troops accompany regulars or worse is a good idea.
The first examle is obvious its not a good place to be, the second the game models quite well. The elite units are more likely to keep performing under fire & produce kills, if they pull off something pretty good the regulars can get a big boost as in suppression lift bringing them back into the action.
