I use only one user variable now:

--8<---------------cut here---------------start------------->8---
(defcustom mouse-avoidance-banish-position '((frame-or-window . frame)
                                             (side . right)
                                             (side-pos . 3)
                                             (top-or-bottom . top)
                                             (top-or-bottom-pos . 0))
--8<---------------cut here---------------end--------------->8---

Which allow to set also the vertical position (top-or-bottom-pos).
See attached patch.
