Narrative:

PF miscounted aircraft in busy pattern and turned inside other traffic. I queried this but had not been paying full attention to radio (pilot is fully qualified). I was looking for traffic but was distraction by an aircraft some distance ahead, apparently not in the pattern. Other pilot and controller apparently under training -- did not help. Must stay alert to sequence calls even when PNF.
