As title says what has been your highest kill count in a sitting in a single gym.
Mines probably 1 or 2 lol my mon arent weak but it is easier to defeat a defender. Also i noticed sometimes if one of my mons die by a defender their kill count doesnt go up. So with that in mind it may be higher.
edit- to clarify i mean when your mon is defending and win a fight an earns a victory point(beside timer when in gym)
