- "Served in the role" means that an individual has formally held the position in an official capacity, whether by appointment, election, succession, or acting designation, and performed the duties of that role for any length of time during the time period.
- If an individual serves multiple non-consecutive terms in the role, they will count once for each term (allowing an individual to be counted multiple times).
- If an individual holds the role temporarily in an "acting" or "interim" capacity for any amount of time, or is formally designated as such, they count as serving in the role.
- Dual officeholders count once per person even if holding multiple titles simultaneously.
- If an individual is appointed but never sworn in, or withdraws before assuming office, they do not count as serving.
