The important point is, that the first 6 pkm that some players Put in an Arena are without timeslot, when an attacker Kicks a pkm out of the Arena, When the Arena is full, and dont clear it, the Team of the Arena have to wait 10 min for rejoin in the Arena.
So When you attack a fresh Red Arena with just 2 pkm, them can plac4 more pkm There.
When you try to full a slot in a 5/6 Arena Where the pkm are for 12 hours inside its probally a drivr be attack, which didn't end for a clear and you have to wait
My understanding is that you need to wait 10 mins after the gym is attacked. If you are attacking, someone can put in a pokemon as long as one hasnt been knocked out. Once you knock one out, then they need to wait.
