It is difficult to say. We have had very few discussions about it, probably because most players prefer to use AA artillery instead, given that it can be used against ground targets instead of just only air targets like nearly all SAMs.
It seems that for the most part legacy data from the old SP series is still used. Revising it is difficult because SAMs performance is complex to assess. There is not a simple benchmark comparable to the "RHA equivalent" which is used for tanks armor and antitank weapons.
