Wrong answer ... going crazy ... must be simple?

Thanks Greg, your reply  is a solution to another issue that has been bugging me. This will come in handy. I've got more resolution on the problem I'm struggling with. Here are the measures in my PBIX:

///
/// Want all of these to be calculated on data sliced by date
///

// This should be the average Talk Time for each worker on each shift they worked
Worker Shift Average =
CALCULATE(
AVERAGE(work_performance[Talk Time]),
ALLEXCEPT(work_performance,work_performance[Date],work_performance[Name],work_performance[Shift])
)

// This is the count of each of the shifts they worked
Worker Shift Count =
CALCULATE(
COUNTA(work_performance[Shift]),
ALLEXCEPT(work_performance,work_performance[Date],work_performance[Shift],work_performance[Name])
)

// This is the average Talk Time of the shifts for all workers
Shift Average =
CALCULATE(
AVERAGE(work_performance[Talk Time]),
ALLEXCEPT(work_performance,work_performance[Date],work_performance[Shift])
)

// Total hours worked by each worker
Total Hours Worked =
CALCULATE(
SUM(work_performance[Shift Length]),
ALLEXCEPT(work_performance,work_performance[Date],work_performance[Name])
)

// Average of the total hours worked by each worker
Average Hours Worked =
CALCULATE(
DIVIDE(SUM(work_performance[Shift Length]),DISTINCTCOUNT(work_performance[Name])),
ALLEXCEPT(work_performance,work_performance[Date])
)

// Total Difference of worker shift average minus the overall shift average Talk time
// Total because this average difference is multiplied by the number of each of the shifts
// the worker worked
Total Difference =
CALCULATE(
[Worker Shift Count]*([Worker Shift Average]-[Shift Average])
)

// The total difference is normalized such that workers that worked less than the average
// time will have an increase total diffence and those that worked more than the average
// time will get a reduction in their total difference
Normalize Total Difference =
CALCULATE(
[Total Difference]*[Average Hours Worked]/[Total Hours Worked]
)

A table of these measures is not really of interest other than to spot check things. What I want is a plot (below) of the sorted normalized total difference over the workers to see how they compare, sort of a ranking. When I do this the normalized total difference measure ignores the shift-wise nature of this calculation and the total difference is simply the average Talk Time for each worker regardless of the shift and the average talk time of all the workers. This is a different calculation and not the one I'm interested in because each worker performs differently on each shift.

I'm sure this is a simple solution I am just at a stand still. I updated the PBIX file

Thanks
