Bobotech, you are right on the down stroke, I am right on the upstroke however, my choice of a longer crank will fail and yours with a shorter crank will succeed. You are right, need a shorter crank, lower the seat. My mistake. I bow to you.

A solution for shorter riders is to raise the crank centerline closer to the seat with shorter arms.
