Butter bread, look at where the unexchanged STARTED the day for miner 2,5,6 that got the good payouts. For those 3 the unexchanged started and finished the same or lower than the day.

Now look at your miner, miner 0, you started with near 0 and ended up with near 0.3. So you need to add taht 0.3 to your 0.32 you got paid out (since it will get paid at a later date). That makes 0.62
0.62 is pretty similar to miners 2,5,6 you refer to.
