We wanted to see how ROS is affected by pool size and pledge, and the results are pretty interesting. Once a pool has about 20M ADA staked, the size of the pool seems to have little to no effect on ROS, and pledge currently has no measurable effect at all.

It will be interesting to see how this graph changes in the coming months as the d parameter continues to decrease. Please let us know if you’d like to see updates to this graph every epoch!
