(2) The presentation of the evidence of the plaintiff and of the defendant, in that order;
(3) The presentation of the evidence of the plaintiff in rebuttal; and
(4) The argument of the plaintiff, of the defendant, and of the plaintiff in rebuttal, in that order.
This order may be varied by the court when circumstances so justify.
