vortex generators in front of rear wheels

Another VG data point to throw into the mix....
I tried Vortex Generators in front of my rear wheels and attempted my first ABA testing (Actually BABA). Found a flat stretch of road, 54 mph using cruise control (never shut the car off so it was the same each time), no AC, relatively calm but humid out. Couldn't help but have a few cars passing me going the other way. I don't know where other folks live, but it's hard to find a good testing spot around here.
Anyhow, these are the numbers:

With VG's
North: 29.8, 30.9, 29.4, 29.6
South: 31, 30.4, 29.9

W/o VG's
North: 30, 29.6
South: 30.7, 30.5, 30

I don't see much difference.
Has anyone got data for VG's in front of rear wheels?
