Fastest Groudon raid ever?

Managed enter the gym, wait in the lobby, defeat, and catch the boss, in 245 seconds (4 minutes and 5 seconds).

Obviously, this is heavily reliant on luck. First you needed to be in a crowded city and have 20 players in the lobby and the bulk of them running optimal counters to shave the battle timer. Then you needed to be able to catch the boss in one shot to shave seconds off in the end.

Wouldn't call this an achievement by any sort but do let me know if anyone's done better :)
