IBM proposal
By my fairly close measurements (taken by hand from the page), the upper-right-hand image on the left side of the graphic provided here, which represents Baumeister's first spring 1972 breakthrough, occupies some two-fifths the area of the original bull's eye. The upper-left-hand image, the second breakthrough, which Baumeister proposed the next day, occupies some 23% of the original bullseye's area.

Why, then, does the article say that these proposals "reduced the area from the bull's eye by one third and then one sixth"? The first of the two appears to reduce the area by three-fifths (leaving two-fifths). The second further reduces it by ~77% of the original bull's eye (leaving ~23%).

It might be more apt to say that the proposals "reduced the area from the bull's eye to two-fifths and then to less than a fourth." Or do I miss something? Mucketymuck (talk) 18:37, 11 March 2021 (UTC)
