Help with RAOBF dis. My measurements are off.

I've found that if the target is fairly close, I can get accurate results if I subtract 500 metres. ie - 2500 metres on the RAOBF is actually 2000 metres. But at longer ranges it gets completely out of whack. 2000 metres and more off.

Could mast heights be wrong, either in the 3D models or documentation in SOANS?

I'm genuinely interested to see if others have tested this.

Please post some screenshots with information on the ship in the scope, and then we can get to the bottom of this.

In the meantime though, I only use the centiradian marks in the scope, because I normally shoot at such low gyro angles that range doesn’t matter. I would suggest you do the same. RAOBF is a handy tool, but there was a reason why they dispensed with it (as well as the split-prism stadimeter) on scopes after 1939 (namely on the C/2 Stand-Sehrohr attack scope you see in game in the tower), because mast heights were seldom known or relied on, nor was that information really needed when in practice they minimized their gyro angles making range have no impact on the lead angle.
