Full raid team

And we're talking gym raiding here, not boss raiding.

Standing six level 40 mangling a gym might be considered a minor overkill, but we got some interesting data anyway.

Berryfeeding is basically noticeable for blissey only. For other defenders the time it takes to leave the gym and reenter it is usually too long for the defender to survive the third combat. Ie the berry feeding player would need to feed a berry betwen each combat and still find out that sometimes a second combat had already occured.

Downing a gym including decent versions of the three big ones, 3.2k snorlax, 3.0k blissey and 1.3k chansey is quick work. Extremely quick work if it's not being fed berries. At no occasion was it possible to spin the gym before attacking it and spin it again after we had populated it fully. Ie time between first attack and last assigned pokemon is below five minutes.

The time used is so short that trying to three-step defenders to kill them in one go is a waste of time unless you verify that someone is actively berryfeeding a blissey at 3.1k or something like that, and even then brute forcing a fully motivated blissey is a matter of some fifteen seconds of time.

The total cost for downing a fully populated and fully motivated gym is aproximately one hyper potion per attacker. Sometimes one revive as well.

It's more efficient to burn through with your machamp than switching to a saner attacker. Gardevoir, gyarados, of dragonite just didn't matter. Despite your being not very effective they go down prior to using a charge attack anyway.

Have fun gym raiding out there.
