Count of Assignees in an Epic or Higher

I am trying to get a count of all assignees that are part of an Epic, or even a higher Hierarchy member as defined by Advanced Roadmaps. I have tried the following and I keep getting unusual counts and cannot figure out why.

Count(
Descendants([Assignee].CurrentMember, [Assignee].[User])
)

Count(
Filter(
Descendants([Assignee].CurrentMember,[Assignee].[User]),
[Measures].[Issues resolved] > 0
)
)

Further, If the total count can include all historic assignees even if not current that would be most ideal.

Any help will be great!

Hi,

The following formula counts the number of assignees for a higher-level issue, including all the assignees from lower levels:

Nonzero(Count(
  Filter(Descendants([Assignee].CurrentMember,[Assignee].[User]),
    [Assignee].CurrentHierarchyMember.Name<>'(unassigned)'
    AND
    [Measures].[Issues created]>0
  )
))

The following formula counts all the assignees, including historical:

Nonzero(Count(
  Filter(Descendants([Assignee].CurrentMember,[Assignee].[User]),
    [Assignee].CurrentHierarchyMember.Name<>'(unassigned)'
    AND
    [Measures].[Transitions to assignee]>0
  )
))

These formulas expect that you have the respective hierarchy member in the report rows:
