This is a repost from the other thread:

I need some insight on the mining process.
I am currently on Uray's pool. Started mining this morning with a balance of 21 Burst. Mined for 4ish hours, had 40+ shares, found a block and only gained 1 Burst.
What am I missing here? I have 1.75 TB in plots which should be around 40/hour per the calculator.

Edit: At block 18303 I went from a balance of 22 to 7 after finding block 18302.
