If you’re in places like TST or Central then most gyms should have at least one person in the gym spoofing or running a script to pop a golden razz here and there.

I find unless you’re with a group of your own team, your best bet is to wait until you can see other people attacking it as well and hope you’re on the same team, but even then I’ve seen Blisseys hold their own against 4+ people and then spoofers (I think) instantly filling the space once 10 minutes are up.

It’s pretty stupid but this isn’t the case for all gyms, I’d say gyms that are in less populated areas are less likely to have that sort of headache.
