Average from feature set using a variable?

Goal: Create a feature set from an intersection of another layer then filter based on a field value. From there I need to define a numeric score value from a string, and finally return the average of the numeric score from the feature set .

The issue I'm having is getting just the feature set to calculate the average for.

//Finds the Neighborhood Polygon that intersects with Selected Parcel
var intersectArea = Intersects(FeatureSetByName($map,"Neighborhoods"), $feature);

//Defines the field to match and set the filter with 
var nbhd = $feature.NBHD;

//Filters all parcels with the same NBHD as the selected feature
var filterresult = Filter($layer, 'NBHD = @nbhd');‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

//This returns the feature set I would like to assign a variable to and calculate an average from

CDU is the field I would like to add a numeric score to average:

if (CDU=="FAIR"){
    var cduVal = 1.25
} else if 
     var cduVal = 1.5
} else if
     var cduVal = 2.5
} else if
     var cduVal = 0.0
} else if
     var cduVal = 2
} else if 
     var cduVal = 1
} else if
     var cduVal = 0.25
} else if
    (CDU=="VERY GOOD"){
     var cduVal = 1.5
} else if
    (CDU=="VERY POOR"){
     var cduVal = 0.75
else {var cduVal = 0}

return Average(cduVal);

If that makes any sense...

Any help would be appreciated.
