What I'm talking about is the width of the view you have when at the periscope. The stock game (and any other mod not using OTC) gives you a width of 36 degrees from side to side (up to down) using the various resolutions a player may choose with his computer system......except one, the 1280x1024 resolution gives you a 38 degree width. The width is commonly called "Field of View" (FoV).
To correctly read an authentic dimension, the FoV should have a 32 degree width. When measuring a degree of angle using a 32 degree FoV, one degree of angle at 1000 yard distance subtends 52.4 feet distance. This means the object that exactly fills the Field of View at 1000 yards distance is just under 1677 feet wide (or long, which ever you like to put it). The game measures this same object at it's incorrect FoV of 36 degrees at 1886 feet long. That's an inaccurate measurement of 209 feet within a target range of only 1000 yards! The inaccuracy is 314 ft for those using the 1280x1024 resolution. Again, I'm talking abut the periscope view. The TBT FoV is worse yet!
My point is, if your getting results that are satisfactory to you in measurements, then perhaps it's not because your measurements are spot on (because I know they aren't). But rather, the game is more forgiving than you think. As my dad told me, "Even a blind hog will find an acorn once in a while".
