Can someone please make this make sense

I’m looking at my premium payouts chart, and the data just straight up doesn’t make sense.

The blue line is projected premium payout amount, and the orange line is my premium payout score for that day. How would the projected amount go back down to zero if its based on the average for the 28 day period before it? Would the average from 6-29-23 to 7-27-23 reaally be that different from the average from 6-30-23 to 7-28-23?


also, another weird thing:
my premium playtime score was 1.05 for a day that I had no premium visits? How does that make sense.
