I don't have Command, but I'm wondering how this works, mostly because of some of the DCS AI's quirks that I'm sure won't all be shared in other simulators, which will have their own quirks instead. DCS SAM's, for example, I find a bother sometimes because they are so straight forward, ie always on or off unless you modify them with scripts or triggers. Flights opposing the SAM's are either SEAD which will usually 100% destroy or fail to destroy them based almost completely on the ARM type they use or they are strike/fighter aircraft which ignore the SAM until being fired on.
Though I guess if it's helping you there's at least something to it.
Sorry for late reply Exorcet, I guess I use it more as abstract in seeing if the mission is feasible with the amount of aircraft or SAMs etc. Obviously its not an end all be all to see if the mission can be accomplished or not. More of an "If I have a flight of 4 F-15s can they theoretically fight through X amount of MIG XXs and continue on or will it be too much"?
You are exactly right however in pointing out the flaws in this logic when it comes to the little things like missile behavior and hit percentages. However in evaluating the force balance in a mission I feel it can help sometimes. Then, there are other times of course
