7 days ago I have have created my 1st post on SteemLeo. It's called "Am I a SteemLeo Orca (an introduction)". It was about 50484 LEO token airdrop I received because I have staked that much PAL in my Steem Engine wallet.

Today this post has paid out and I should have received 148 LEO tokens as author rewards. Since I also selfvoted this post I got an equal amount of LEO tokens as curation rewards. So that's total of 297.20 LEO:

I know I shouldn't have received all the payout because there were 326 other people upvoting it. But it doesn't really matter.

What matters is that I received 331 LEO tokens today (not 297 LEO):

It seems that I was rewarded some additional tokens as well.

Why?

Maybe it's because it takes a few weeks for reward pool and reward system to stabilize.

Maybe it's my curation rewards when I upvoted other people's posts?

I do mine some LEO tokens but the amounts rewarded have been from 0.83 LEO to 1.67 LEO for several times a day.

What's your take on this? Why did I received some additional LEO for my first post?
