don’t want to hijack your awesome graph and topic, just add it as an idea for future such graphs.
With the given randomness (good/bad luck) a pool can show up in different areas in this graph.
Blue is what I would call the expected performance.
Below 1% it is just OK. not more and not less. and hopefully, they can find their way upwards to the saturation point in this area.
Saturated pools above 1% have more than enough slots to reach the maximum rewards. A pool surpassing 2x the saturation point can miss to fill 50% of his slots, and still reach the maximum in rewards. The only drawback for this “assurance” is that rewards are divided into more stake. So guaranteed but fewer rewards.
These Pools are either whales or good marketers.
Red area instead is where pools - for whatever reason - don’t produce enough blocks. They under-perform.
Green area instead is where the pools seize every opportunity (assigned slot) in an extraordinary reliable way and produce blocks like real champs. Maximum rewards for the early delegators. Until other take notice and re-delegate, by pushing this pool up in the blue saturated area.
