it actually cut out half of my post
.
I was saying that people should be rewarded for defeating the encounter. If the party meets the person again another time, the enemy will be at full power and therefore full experience. If a party meets the person later and the person is still down health, spells etc... Then they should get the complete xp at the time.
I suppose if a party knows that they are going to be fighting an encounter where they have aforementioned knowledge, and are prepared for the encounter totally, they should not be able to get max xp because there was not as much of a challenge.
A party fighting a purple worm, but the party is flying should not get as much xp for defeating it unless the purple worms actually did something to the party, like poisoning, or eating party members.
