StatRRefs is the number of references to a def from the same repository in which the def is defined. It is inclusive of the StatURefs count. It is only computed for concrete defs (see the docs for DefKey) because otherwise it would count 1 rref for each unique revision of the repository that we have processed. (It is easy to determine which specific commit an internal ref references; we just assume it references a def in the same commit.)

StatRRefs is referenced in 1 repository
