civicrm_mailing_bounce_type.threshold = 30 for 'Away' is that correct?
I searched for "civicrm_mailing_bounce_type" and could find no issues. @seamuslee wanted confirmation that '30' is the correct number of civicrm_mailing_bounce_type.threshold for type=2 "Away".
I can confirm that 30 is the default value in 5.6+, if not older. This default was changed from 3 to 30 at some point, not sure when. 3 is listed in the documentation, and there is a PR to change that part of the documentation.
