Thanks yes I don't need that other stuff
In the study I used it was noted that with deep dimples even though the downforce overall increased drag dimples weigh less than spoliers so efficiency for performance vehicles was increased.
For my car however that's not neccasary. It was not easy, there is only a narrow band of increased efficiency but mine were designed for a descent starting yield of 38mph, my average speed. Much below this and especially below 25mph and they become almost of no benefit. I decided that in a real world enviroment despite crosswinds that it would help. Even below 25 sometimes you will have headwinds and there are no negative effects at any speed.
I did not test my car before and after as I cannot achieve exact similar testing, I just create what makes sense with the information I have. Comparing my nearly 20 year old gen 2 to a hired new 'eco car' however I'm doing something right
