Healing hp/mana cost vs. Shm wiki page

[Tann]

Quick question on which of these is correct, for my napkin math theory crafting work sessions

from the main part of the Shaman wiki page:
A Shaman can convert Mana to HP using various Healing spells; the theoretical best high-bandwidth hp:mana conversion ratio being 6.0 (Torpor):

Greater Healing (LVL 29): consume 115 Mana, gain up to 350 hp (conversion ratio is 3.04 hp:mana)
Superior Healing (LVL 51): consume 185 Mana, gain 600 hp (conversion ratio is 3.24 hp:mana)

or the page for each spell:
Greater Healing = Increase Hitpoints by 288 (L24) to 300 (L30) for 150 mana
Superior Healing = Increase Hitpoints by 565 (L34) to 583 (L40) for 250 mana

Cheers~
