If the payout is reduced the dollar why?

If the payout is reduced the dollar why?
Suppose you have a 10 $ at a post
But when the payout is done after 7 days
Get $ 3.75 as sbd, get $ 3.75, as sp.
3.75 $ + 3.75 $ = 7.5 $
The post was $ 10. $ 7.5 to $ 7.5 and $ 2.5?
Athour (author) receives 75% of a post's total dollar
And 25% gets curators (who gave upvote at the post)
When posting again 100% of Steam power marks on it, 75% of that post goes to sp.
Again, there are less than $$ in the calculation.

Again, there are less than $$ in the calculation.
This is because if you post Up with your Upvote post, then the payout ratio will be changed (50% -50%).
Or more and less. If you get a payout, then $ less.
In order to keep the ratios off, you will not vote for 30 minutes before your post.
Then the ratios will be fine.

GOOD LUCK
