Original sentence: Consequently, large-format technologies like IMAX favor a 4:3 format.One can further criticize the supposed superiority of widescreen by calculating the area of different aspect ratios that have been constrained by the size of the diagonal and not the horizontal.That is, if you compare rectangular shapes with the same diagonal size, the aspect ratio of 1:1 will have the largest screen area
Edited sentence: A rational comparison would have been calculating the area of the two screens with different aspect ratios being constrained by the size of diagonal.By that argument a screen with aspect ratio 10:1 would be even more superior.Finally, the ultimate viewer experience technology -- IMAX -- is using 4:3 format.From technological perspective, lower aspect ratio screens is cheaper to  manufacture.It is an elementary mathematical fact that among all rectangular shapes with the same diameter the the aspect ratio to 1:1 has the most area.The method shown above for comparing aspect ratios doesn't withstand any scrutiny
