I just spent 20 minutes googling and searching Bulbapedia for the answer to this but I have come up dry, so I'm asking for your help, fellow /vp/oreons.

How many potions/super potions/hyper potions/full restores do the various gym leaders have? Is there a pattern to it that's the same every game? The only mention I could find is that the twin gym leaders in Hoenn have two hyper potions.
