But shouldnt everyone's bitcoin payout be relative?
So if someone has 1000khash and they get 0,01btc on 21dec 2:30am, then if another user has 3000khash he should get 0,03btc on 21dec 2:30am?
If one person mines for 24 hours and I mine for a week straight with an equal hash rate then it is entirely possible for me to get three times the payout on Dec 21st since coin I mined on Dec 15th could finally mature and pay out. Another possible scenario is that the coin I mined on Dec 15th wasn't very profitable at the time I mined it, but the value tripled by the time it was exchanged. It could go the other direction too. Some crazy coin might be worth a fortune on Dec 21st, but by the time it gets exchanged on the 23rd it is near worthless. The gain or loss on any kind of currency transaction is only theoretical until it changes hands.

Chad's point is right on - nothing gets "reset" after the payout... coins are carried over to mature and exchange. Also, not all MH/s are equal. What counts is accepted shares: depending on your latency and/or just plain luck, you might have more or less accepted shares than someone else with the same nominal hash power.
Your final takeaway should be: over time, everything evens out. Just wait and see.
