In Emacs around me (25.1 on Mac, 25.1 on Windows), the following lines
give me overshoot for each scroll-down.  Is not the case for you?

(dotimes (ii 10)
  (scroll-down 1)
  (set-window-vscroll nil (1- (frame-char-height)) t) (sit-for 0.05)
  (dolist (vs (reverse (number-sequence 0 (- (frame-char-height) 2))))
    (set-window-vscroll nil vs t) (sit-for 0.05)))
