Yeah, your payout is proportional to your stake of SP.

Here is a quote from our FAQs:

How are payouts calculated and when are balances payed?
At the beginning of each month a snapshot of all accounts who voted for the witness is taken. Depending on how much Steempower you hold at this time, your proportional share of all earnings for this month is calculated. You can always check the data right here.
Payout for each account automatically happens on the 1st of each month for all earnings accumulated the month before.

I know it can be frustrating for minnows who doesn't have large stake of SP, that's why we introduced the Community Bot - you'll receive at least upvote each weak just for participating - your SP doesn't matter in this case - everyone is treated equal.

Are you and @isnochys the same person?

I'am pretty sure they don't :)
