I have reconsidered at length on the question of the Short-Greek Alphabet, and have reverted to the original 10 that I had earlier — A, D, E, K, L, N, O, P, S, and V, with a few qualifications.
My earlier observation was correct, and I am sure, that the best alphabet bears letters with no curvatures at all — meaning that the capital “D” is triangular, the “L” is an inverted “V” (exactly), the P is actually written just as Pi, a “square” shaped U that is inverted, and the S is really a Sigma, and looks like a reverse (mirror) image of a 3, that has diagonals meeting at the middle (and no curves), and the Upsilon is the “V” (meaning this is like an English “U” in its sound and functionality).
The reasons for this change stem from the fact that (when writing) the principles of clarity, and necessity, require the letters to be as minimal as possible in their construction. These precede the principle of uniformity, which seemed to require the earlier (more triangle-like) and somewhat odd-looking letters.
It is also true that, when typing, the number of PENstrokes necessary to write a letter makes no difference, since each letter forms by the press of a single button on the keyboard. Technology, and divinely-ordained progress, have outdone the question of “how many penstrokes” a letter has.
