Utilization Report: Measuring Percent as Whole (Don't summarize measures!)

So I've struggled with this utilization report for a few weeks now, and every time I think I have it, another problem crops up. 

I've got it very simple.  All data pull from a few different tables, but the main one is called (for now) Append1.  Here are my columns (this table is unpivotted from tables with dates as the columns):

• Full Name - The employee name
• Project - The project the employee 
• WS Date - The WS dates for each project that the employee will be working
• Projected Hours - The hours for each week on each project will be working
• Measure: [Calc End Date] =  CALCULATE(MAX(Append1[WS Date]))
• Measure: [Calc Start Date] = CALCULATE(MIN(Append1[WS Date]))
• Measure: [Calc Projected Hours] = CALCULATE(SUM(Append1[Projected Hours]))
• Measure: [Calc Possible Hours] = IF([Calc Start Date]=BLANK(),BLANK(),(DATEDIFF([Calc Start Date],Append1[Calc End Date],WEEK)+1)*40)
• Measure: [Calc Utilization] = CALCULATE(DIVIDE([Calc Projected Hours],[Calc Possible Hours],BLANK()))

So basically, Calc End Date & Calc Start Date figure out when the first and last date of the employee are (within a measured date slicer) and then Calc Possible Hours takes the date difference and multiplies that by 40; so they could work 40 hours per week within that date range.  Calc Utilization figures out what the utilization rate (%) is.

This works great in table forms (when I cross reference it by Full Name).  But when I try to aggregate it by Area (from a related table) or even in whole (what is the overall utilization rate), my measures just add up all the utilization rates (%) instead of doing an average of the utilization rates (%) which is appropriate.

Here is the current report.

I'm tearing my hair out here.  Please help!
