When the FO has a line of sight with the target, you can easily adjust two or three times before the delay reaches 1.0. And further, when your FO has a line of sight with the target, the scatter if far less and in fact most of the time the center of the barrage hits right on the hex you ordered it in.

Now, it could be argued that it is in no way realistic to have more artillery scatter or less accurate fire or more delays when firing at targets the FO doesn't have a line of sight to. And yeah, it isn't. It takes no longer to order a fire mission to a target behind a hill than it does to a target on top of a hill. But it could also be argued that it is in no way realistic that the FO can spot the center of the barrage for a fire mission he can not see. Or that he can then adjust the fires based on the observations he did not make.

So if you ask me, it's a pretty fair abstraction and a reasonable counterweight to giving the FOs the uncanny ability to accurately adjust fires they didn't observe. Perhaps the most realistic approach (I'm not actually suggesting this to be done because if you ask me the current system is way better) would be to make the explosions of fire missions the FO doesn't have a line of sight to invisble to the player and have him adjust based on a hunch. Because that's how it would go in real life. Unless of course the FO is a superhuman who can spot the trajectory of the grenades while they are in the air and accurately calculate in his mind where they are gonna hit. Or hear the explosions and use that to determine the exact range and bearing to the center of the barrage.
