.2 * .33 =.066

But you multiply that by damage and number of targets hit:

.66 * Damage * targets = HP total.

Also keep in mind that Minions typically have less Armor and Magic Resist then champions, so the Damage you deal won't be the same AND champs have different resists. So if you do group up minions AND champs you end up with:

.066 * (Damage to minions * number of minions) * Damage to champ * (Damage to other champ if applicable) * damage to as many more champs that are applicable= total HP gained.
