Intrestingly I found out (by trying in game) that
small potions made at crafting LVL 2 gave:
Mana 40
Health 40
!! but small Potions made at crafting LVL 3 gave:
Mana 60
Health 100
=> this is the same as normal potions I brewed at crafting LVL 3 !
I made them at the same time with the same ingredients (except the seize of bottles) and tested afterwards.
and it is actually the same effect for 1/3 of weight!
