Not trying to attack you. Just responding to your idea with some feedback.

You'll do fine with your thesis. You'll write drafts. You'll get feedback. Your next draft will improve. Write lots of drafts. Is this project part of the thesis?

Also I installed them with the high side of the vg facing forward to center of the car rather than backwards away from center.
How did you do your testing? There are lots of variables, not just placement of VGs, that could contribute to changes in FE. I am not saying I think the VGs did not work for you.
See my car's mod & maintenance thread and my electric bicycle's thread for ongoing projects. I will rebuild Black and Green over decades as parts die, until it becomes a different car of roughly the same shape and color. My minimum fuel economy goal is 55 mpg while averaging posted speed limits. I generally top 60 mpg. See also my Honda manual transmission specs thread.
