An easier way to convince people would be to shave a chimpanzee and
measure the drag and then compare it against the drag without the
shave :-)..

How about replacing the sealskin with chimpanzee fur? How does
that work?

PS. What is "reduction of speed pulsation"? I assume that the
dummy had the shape of something like a human. Did it?
