When I did auto targeting that
"S" light ( I assume S= solution) in the middle of the fire buttons would indicate wether my solution was POOR or Good and if the target was locked or unlocked.
Now when I do manual targeting that light still indicates locked and unlocked but it never moves from POOR to GOOD status. ( ok...ok... I know there is material there for a personal slam

...but read on... )
Even today when I put 4 torpedos into a Modern Passenger Liner at 1200 yds doing 17 knots...it still read POOR Solution as I was firing.
Now why is that?...
