Yeah, I'm not a fan of the SCAF mod. It's way too easy for us to find the range of a target because our recognition manual has every ship in the ocean with fairly accurate measurements. Contrary to popular opinion, the Japanese Navy did not rent us the Akagi to take it to San Fransisco bay and measure the heights of all its masts, the length of the ship and take great pictures of. And they sure didn't rent us their merchants for the same purpose!
The fact is, our ONI manual was a by guess and by golly thing with a small subset of the ships likely to be encountered within its pages. If you found your target there, you could almost guarantee then information was wrong: wrong length, wrong masthead and cabin top heights, etc., because the Japanese knew what we knew. Then they changed funnels, altered mast heights, actually built scale model ships of larger ones so we would misidentify and get the range wrong by a factor of 3 or 4!
So you can see that the SCAF mod is THE OPPOSITE of the way we should be going. We sit around grousing about how we can get 100,000 tons in a cruise when very few subs did that during the entire wartime. Well, there's a large part of the answer. We cheat.
The real answer is to get rid of SCAF and introduce the Real Recognition Manual, with the exact crap our sub captains were forced to deal with in WWII. And watch those tonnage totals go down!
This has been a paid announcement of the Dick O'Kane Targeting Company, seeking to cripple all other forms of targeting leaving players with no choice but to use the vastly superior Dick O'Kane targeting technique. There is method to our madness.
