About your saturday thought on over delegation, what would really help is an app showing this data in real time.
Put a simple green / orange / red dot next to vote power to show when a provider is still efficient for new delegation, close to the effective cap, or already over-delegated.
And add one more key metric: a delegation efficiency rate. Not just the provider reward rate on paper, but how efficient a new delegation still is after fee and after the effect of over-delegation / cap.
For example, a provider may show 7% on paper, but if it is already too crowded, a new delegation may be far less efficient in real terms.
This would not replace data quality metrics. It would complement them. One metric for provider quality, another for delegation efficiency.
That would help users move toward other reliable providers too, not only the biggest names, and in the process improve data quality and network efficiency.
Just an idea ๐
