Anyone who has seen the original MS (or the recent facsimile), or, in fact, has taken more than a passing look at the online scans will see that no two folios are of the same size. They are only approximately rectangular, and many are not even nearly rectangular. Differences occasionally are several cm.
It is therefore obvious that the dimensions given by Beinecke are some approximate average.
Comparing them at the millimeter level with other manuscript is meaningless.
By the way, my powerpoint file was not meant as a presentation. I used powerpoint because it allowed me to draw rectangles of which I could specify the exact dimensions on a 1:10 scale.
