It doesn’t actually mutter the “words count” (not much at least). Ask yourself theese questions:
-
Did I say everything?
-
Was I clear enough?
-
Did I speak any useless chit chat?
If the answers are not, in order: yes, yes and no… you have to re-write something.
PS in doubt remember: better a text with too many too short paragraphes than a text with too long paragraphes; the latter are very hard to read
