a=recovery amount
z= vit
x=inc. hp recovery lvl
c=potion research lvl (if the item is a potion and you have it)
v=other modifier from equipment
b=1.5 if ranked potion, 1.0 if normal/other healing item
{[a*((z*0.02)+(x*0.10)+(c*0.05))]*b}*v
example:
my RK's vit = 100
has inc. Hp recov 10
using a ranked white potion
and wearing an RWC cap which has a 100% bonus to white potions and red potions
white potion's max recovery is up to 405
using this stuff, my RK heals at about 3k+ HP on White Pots but they're so Heavy and quite expensive 
{[405*((100*0.02)+(10*0.10)+(0*0.05))]*1.5}*2 = 3645
kinda OP but yeah, the Ranked potion modifier is quite a bonus, now if we add Flamel bonus (x3 / +200% condensed bonus increase) instead and using white condensed that's also ranked
{[405*((100*0.02)+(10*0.10)+(0*0.05))]*1.5}*3 = 5467.5
that's why the card costs a lot 
but note that it takes up quite an important slot on your equipment
