Countax / Countx is not funcitoning well

Hi,

I have an issue regarding creating correct dax formula. 

I have two tables.

• Team table: unique identifier
• All data table

I want to get the total right, to show how many people who have at least 75 reviews.

Below is the formulas I've tried, but non of them works to get the total right. 

Formula 1 tried: 

• CALCULATE(DISTINCTCOUNT('All data table'[WorkerID]), FILTER('All data table', DISTINCTCOUNT('All data table'[Reviewid]) >= 75))

Formula 2 tried:

• Var Review 75 =  COUNTAX(VALUES('All data table'[WorkerID]), DISTINCTCOUNT(All data table[Reviewid]) >= 75)
  Var CountTotal = SUMMARIZE('All data table', 'All data table'[WorkerID], "WorkerIDs", Review75)
  Return
  IF(HASONEVALUE('All data table'[WorkerID]), Review75, COUNTAX(CountTotal, [WorkerIDs]))
  

Formula 3 tried:

• IF(HASONEVALUE(Team[WorkerID]), CALCULATE(DISTINCTCOUNT('All data table'[WorkerID]), FILTER('All data table', DISTINCTCOUNT('All data table'[Reviewid]) >= 75)), CountX(DISTINCT(Team[WorkerID]), CALCULATE(DISTINCTCOUNT('Team'[WorkerID]), FILTER('All data table', DISTINCTCOUNT('All data table'[Reviewid]) >= 75))))

Formula 4 tried:

• IF(HASONEVALUE('Team'[WorkerID]), IF(DISTINCTCOUNT('All data table'[Reviewid]) >= 75, 1, BLANK()),

countax(DISTINCT('Team'[WorkerID]), DISTINCTCOUNT('All data table'[Reviewid]) >= 75))

 

Below is the result

 

The total is not matching the calculation result, should be 4 instead of 8.

The purpose I tried all different formulas is to get the total right, which should be 4.

I was using countax and countx, and none of this formula works.

 

Could you help me with the formula please?

 

Thank you!
