Actually, according to this Japanese MH3G wiki...

(go to monster details for more specific damage numbers/formulas)

... Brachy gets less damage from Slime explosions. If the source is reliable, it seems that slime deals different damage depending on the monster.

But I guess the extra damage to part durability helps quite a lot too since monsters would flinch/trip a lot.

OT: I always fight Alatreon near the ballista binder, somewhere at the middle top of the map, near the exit from the base camp. When he does that pre flight dance, I immdeiately get on the binder and shoot him down for a couple of seconds of uninterrupted free hits. :D
