Is there a standard as to how many angels can dance on a tertiary bevel before a blade needs to be reground or is it when the tertiary bevel fully overlaps the secondary?
These are the kinds of pondering that might keep me up at night if it weren't for being satisfied with a flat as possible bevel, as long as it cuts as well as possible or needed with my skills.
