Spoiler or not to spoiler

Moving onto the read end of my Z, trying to determine if my hatch spoiler would in fact decrease Cd as wind tunnel tests have shown in this post here

Windtunnel Test Data - HybridZ

tests #9 to #12

I own two hatches, one with and without. Im currently finishing the spoiler-less to be installed pending what everyones thinking.



Take a look at the data, pics are lower down in the same post. Would deleting the spoiler in theory, assist mileage?
