Conditional formatting base on static average for week

[Anonymous]

Hi I have a table visual in my report which repersents the raw dataset to users so that they can drill down to it. 

The logic is to highlight rows which are have "duration" higher than the average for its category ("banneraverage"). Desired outcome is as such with my manual highlighting.

I seem to not be able to achieve this as when I put in the condition it will always outcome to be lower than duration as you can see by the third column with normal dax AVERAGE function.

BannerAverage = CALCULATE(AVERAGE('Truck Turnaround'[Duration (Mins)]), FILTER(ALLEXCEPT('Cat'),'Cat'[Banner]))

I have also tried 

Condition =
VAR _PNSavgdur = CALCULATE(AVERAGE('Truck Turnaround'[Duration (Mins)]), FILTER('Store Mapping', 'Store Mapping'[Banner] = "PNS"))
VAR _NWavgdur = CALCULATE(AVERAGE('Truck Turnaround'[Duration (Mins)]), FILTER('Store Mapping', 'Store Mapping'[Banner] = "NW"))
VAR _4SQavgdur = CALCULATE(AVERAGE('Truck Turnaround'[Duration (Mins)]), FILTER('Store Mapping', 'Store Mapping'[Banner] = "4SQ"))
VAR _duration = SUM('Truck Turnaround'[Duration (Mins)])

RETURN IF(_NWavgdur > _duration || _4SQavgdur > _duration || _PNSavgdur >_duration,1,0)

 Then use rule conditioning but think this will also not work  because of the sum aggregate function.  And values disappears. 

Please help? As this seems like a rather simple thing to achieve but I am unable to achieve it.
