Ships length past the vertical graticule / seconds x (3600/1852) = speed.

caveat: ship AOB should be between 60 & 120°, and the sub setting still or No faster than 1 kn.

i.e., T2 = 152.7m / 40 sec. x 1.94 = 7.4 kn.

I never worry about 'range' if the target fills half the scope @ x6 it's close enough for a kill. Speed & AOB are the only things of concern.
