Purple: Daily rewards Teal: 7-Day average rewards
I copy/pasted this chart from my BraiinsPool dashboard. I've been mining with roughly the same amount of hash rate for the entire duration shown in the chart.
All of the random spikes indicate the PPLNS mining rewards strategy, while the stable line indicates the FPPS strategy. It becomes obvious when this transition occurred.
Also, you can see when the most recent halving occurred, with the bonus spike on the first day or so after the halving when the fees went through the roof for a short period.
Enjoy the chart, and feel free to ask any questions!
PS: Yes, I omitted the Y-Axis, so I don't fully share my total mining rewards ;)
