Pokemon-go – What determines whether a gym shows its banner

In my area, there are currently three Mystic gyms, and two have their banners shown while the other does not:
What determines whether a gym shows the banner of the team that controls it?

Based on the evidence being gathered in this thread, it looks like a gym will display banners if the total CP of the Pokémon in the gym surpasses 8000.
Just in scanning over the active gyms in the area, it looks like Banner Flags show up when the total CP of the defending Pokémon passes a certain number. There're two that I can see from here with only 3 Pokémon on them – one with flags and one without.
Has banner flags
2985+2682+2882=8549 CP
Dragonite, Gyarados, Snorlax
Doesn't have banner flags
2992+2362+1686=7040 CP
Tyranitar, Rhydon, Gyarados
Gym I could see from here had no banners when there were 3 pokemon in it: Rhydon 2744, Snorlax 1884, Gyarados 2098 = 6726.
A 4th was added, Vaporeon 2079 to bring the total to 8805 which raised it and banners are flying.
The two gyms near me are both bannerless with totals of 5286 (2 players) and 7551 (3 players)
I've got a Gym that was at 8100 & 4 Pokémon and had banners, and is now at 7800 with the same 4 Pokémon on there, but all the banners have gone.
I'm pretty sure a Pokemon needs to be at full HP to be placed in a gym, so the reason yours wasn't available was because it was hurt from the previous battle. Heal it to full with potions and it will be available.
On average, there is a slight disadvantage to picking the weaker team, but not one that will completely affect your game.
For most of the game, your team affiliation will either not affect you (spawn/catch rates). There used to be rumors about giving you a perk for that team, but there's been no real evidence since. (Even after the game was reversed engineer to see more of the "gears", like how many steps to make a spawn call.)
The disadvantage comes from the lack of opportunity to earn the Defender's Bonus that Gym Leaders get for having a Pokemon at Gym. If you join a team that is the weakest in your region, then you and your team will have issues in holding onto Gyms. (whereas the teams with more members can statistically attack, take over, and fortify easier.)
The biggest takeaway though is that this is only an opportunity cost. The weaker team might be stronger a mile away, the stronger team might not frequent the area you are as much. The number of variables are unlimited as to that the weakest team might control all the Gyms of a city since their members are organized. There's no hard-set disadvantage, just a fluid difficulty curve.
