Healing Monster Chance

[bury]

Hello, I need to know how is calculate this chance:

<defense name="healing" interval="1000" chance="20" min="3000" max="6000">
			<attribute key="areaEffect" value="blueshimmer"/>
		</defense>

That 20 is 20% of probably of healing or what? because in the loot, the chance is 100000 to indicate 100%

Thanks

there is a chance of 20% every 1 second that the monster heals between 3000 and 6000.
