 Replying to [comment:1 asn]:
 > Hm, I don't really know which static values we should consider normal in
 this case. Maybe #8145 is kind of related?

 Only if you can translate that into upper/lower bounds I can write into
 the consensus-health checker code.

 detection (a dynamic system) to find abnormalities in those values.
 (Although, the current anomaly detection system we have for censorship
 events does not work too well, does it?)

 I hope static bounds will do the trick for now.  I agree that we're not
 very good at writing anomaly detection systems.

 I'm attaching a plot of flag thresholds reported by moria1 and gabelmoo,
 which I'm going to renew in 1 week and in 2 weeks.  Then we can define
 bounds when we want to get notified.
