you have a high opinion in yourself but dont seem to be able to use basic logic,simple reasoning and common sense. you'r also confusing yourself with all the little numbers you are quoting and dont understand the context.

Size to the screen for a FOV of 30° is so:
Dist = 9.58/tgt(30°/2) = 35.7" (or around 90 cm... which is approximatively the distance from my eyes to the monitor... )

all you have just done is calculate what distance you need to sit from your 22' monitor so it is equivalent to a 30 FoV, nothing more. that doesnt mean 30 FoV is "normal" to use in il2.

no that doesnt prove anything, and isnt relevant to anybody else using il2, all it does is tell us how far rama sits from his monitor.

and i dont believe you in that regard either, it is not normal for the average pc user to sit about 1 meter from a 22' monitor while gaming or using a flightsim, and you couldnt either read normal text in windows like that, and you are sitting to far from the screen to see normal detail in video and gfx images during other pc use.

what i suspect you are doing by claiming to set the 30 FoV and use il2 in that manner is "cheating", because you might be setting that 30 FoV and then additionally sit much closer then 1 meter to the screen so there is an additional magnification factor in the objects you look at in-game (the linear size of the objects will now look larger to you). but you cant fly like that and still claim to use the sim correctly, so your argument is mute.

a ballpark normal viewing distance from an lcd monitor with 0.25/0.30 mm pixels is about 50 or 60 cm (as was explained in detail in an earlier post here).
- only users with extremely large lcd monitors will sit a bit further away, for ex with a 32 or 37' westinghouse pc monitor might the user sit about 1 meter away (note those still use 1920 x 1200 resolution, so the pixels will be extremely large at about 0.50 mm and if you sit to close it looks very blocky
- even those that use a 30' lcd pc monitor will usually sit at similar distance, because the pixels on it are similar to a 20' monitor, and text size will therefore be the same (the 30' user just gets a much bigger desktop)

i dont think you will find a single other il2 user with a 22' monitor that sits about 1 meter from his screen, so by your own logic all those other users will see things incorrectly and objects will be shrunk, since they will be using a wider FoV and sit closer to their monitors.

sure, i believe you

and of course, you are trying to have a meaningful discussion while pretending not to read what others say, but still claim only you is right eh
