Okay, I'll bite... a couple of reasons I'd challenge how you've arrived at that conclusion...
You're basing this off a redrawn blueprint you have found. In fact, going by the text showing through from the other side of the page, in this case it's a Russian book, which means it's not an accurate original factory drawing (which are about as rare as hen's teeth anyway)
Another point.... the view you're using in game looks to have a fairly wide Field of View. If you were to narrow this down a great deal, you could create a view not too dissimilar to that of an ultra-telephoto lens, otherwise every screenshot you're taking is distorted if you want a genuine side profile view.
What would be best to do is find a long focal length photo which is side on of an actual Mirage F.1 and compare that way. (Minimum 2/300mm is probably best)
TL:DR... Trust real photos... not redrawn blueprints
