I love this feature in the DGUI !
During WW2, the simplest practices, were also the fastest and those with the least error. the most efficient.
here we see in the periscope the graduations are in mils too (normal graduations + mils graduations). first screen we see 110 mils for the ship (wich has mast high= 22.5). and fast looking in the x6 table we see immediatly 110/22.5 = distance 800 m !
second screen with obs periscope. x1.5 same target ship, same distance. we see in periscope high = 30 mils. ship high is 22.5. and in the x 1,5 table we see immediatly 30/22.5 = distance 800m !
