Instant KO with 3 accounts

If you leave a gym fight, then rejoin, rather than putting you back in the same fight, the game creates a new instance of the fight for you.

- Group of people start a fight.
- At least one player stays in the current fight, the rest leave and start a new fight.
- If the defenders are at 2/3s or lower motivation, two groups finishing the fight as close as possible to each other will each take off 1/3 motivation and knock out the defender.
- If the defending team is using golden razzberries at 2/3s to always keep the defenders at full motivation, then you need to make three instances.
- After the first defender is knocked out, you have 10 minutes to knock out the remaining five defenders before the current defending team can add new defenders back into the gym.
- After the separate instances defeat a defender at the same time, groups should sync back up in the next fight. Start the fight, then repeat.

The procedure is as follows:
1. 3 ppl start a battle.
2. 2 of them leave and start a new battle, this will open a new battle and they will not rejoin the already opened battle. The one that left fighting bring the chansey's health to within a charge move and wait, don't finish the battle.
3. The 1 of the 2 in the new battle leave and start a new battle.
4. All 3 trainers synchronise to finish at the exact same time. Chansey is beaten 3 times and it's motivation drop from full to 0 without a possibility to GR.

However. If you go in, in the middle of someone doing this you have a chance at erorring them out if you kill it. I dont know how it works exactly but i was able to keep a mewtwo gym blue after a shady valor guy rolls up and attempted this trick.
