Thanks for that. I didn't know engine tuning would help that much.
You are correct that wind is usually a bad thing.
I also think that weight is important. A high Sectional Density is better in the long run than light weight. It will extend the coast down distance. That is why in gliding competitions the gliders carry up to 500 pounds of water ballast.
I tried doing a coast down to figure my Cd ratio and found that a 6 gallon water can in my Metro changed the results significantly. You must really have an accurate weight to do those calculations.
