Right, it means when we find a block, that's how much you will get as a payout.
This statement is confusing to me (as a newbie). Seems like you should have said; If we find the current block (that we are working on), that's how much you will get as a payout.
The reward for each block changes and more than likely you will not get that amount, could be more or could be less.
Now if you changed derp to show the payout based on the minimum block reward of 12.5 you could state it the way you did. But, you would need a new field to track the variable payout from fees included in the block.
IMHO
