What's the real way to bust tanks? I've been playing MvM for years and i've heard all sorts of different tricks and remedies for killing tanks faster as Pyro

Some people recommend looking straight up from the front of the tank and claim it does more damage


Some people say to shoot directly at the tank from behind because the flame particle linger for longer

I even think the fastest method is hugging the side of the tank because it's closest to the tank's hitbox


But has there ever been scientific research on what the actual best way to kill a tank is as pyro?

I've even heard some speculate the dragon's fury is better than the phlog
