I think you left out some steps. I tried modifying Glen's test above
to give approximately the same number of abbrevs

;; 17576 abbrevs
(dotimes (i 26)
  (dotimes (j 26)
    (dotimes (k 26)
      (define-abbrev emacs-lisp-mode-abbrev-table
      (concat (char-to-string (+ 97 i))
              (char-to-string (+ 97 j))
                    (char-to-string (+ 97 k)))
      "who cares"))))
