I suspect that my car may have had more to gain, percent-wise, than your Insight:

The main difference being the cross sectional area at the rear where each of our OEM shapes end and where the tails begin (or began in the case of my prototype tail, which has long since gone out with the recycling). I suspect the area at the rear of my car is bigger - thus more room for improvement.

I'd be willing to calculate/estimate that rear area of my car if you're interested in comparing. I bet this has probably come up already.
