How are Ingress Top Agents chosen

Top agents are calculated based on their total MU throughout the entire cycle. It's being refreshed every CP. Top agents list doesn't show the team's success. It's a total personal list. If a player creates the same field 10 times during the cycle but this field doesn't stand up at the end of any checkpoint this player will be listed accordingly on the top agents list but the team won't get any points from those fields
