Why people argue about this
People often assume that a 4-10 minute match in Jiu-Jitsu (AJP) means exactly what it sounds like—four to ten full minutes of grappling without breaks—but actually, these time limits are per belt level and can be broken up into rounds or periods with breaks for rest. The confusion arises because the verbatim rule doesn't specify how the total time is divided among matches.
