I noticed this happens on the build_metrics framework, for at least the compiler warnings and installer size tests.

Recent examples, were I had to manually create the alerts:

we are getting improvement alerts for the other frameworks still, so this seems like an edge case. Would we expect to see improvement alerts for <2%, that is our default threshold for an alert unless otherwise specified.

The 13% improvement should have been alerted on.  Maybe there are messages in the log file?  Were data points backfilled here and we got the notification >2 weeks later because we were backfilling 2 weeks later?

This is marked as a P1 but isn't assigned to anyone. Can this be marked down to P2 or P3?

Yes, I'd mark it as P3.
