Atomskytten. You have little understanding of three-dimensional perspective. You can't just go measuring things as they will not give you correct values.
Recoup. You have little understanding of the zoom function. I advise both not to continue in further argumentation with Phoenix Dragon, as he has much more understanding. Still, he will probably be a gentleman and will try and explain again?
I believe my observational skills of using zoom to close my vision around my iron sights is not something that requires more or less understanding of the function in and of itself. Do not belittle someone else in order to discredit what they've said, as it adds nothing of merit to the discussion or tells me why I should be wrong in this case.
r5cya is right, of course, that popping your eyes out of your head doesn't give you the same results - I was being silly and thinking in terms of cartoon physics. However holding one's breath when aiming does not create the conditions that are created in the game. Everyone lived with this function in RO:OST, why is there such adamant desire to keep it?
hockeywarrior hit it on the head.
