just an after thought, why not make a little layout (or rob somone else's it matters not, or just edit a track) find out where the governing body for drifting competitions (such as D1 grand prix) says the line for the most points is, then set up some posts on aforementioned line (as in the green ones that you can place with the editor and knock over)
the drift points thing will say your angle, try to get the highest angle and hit all the posts
Then bobs your uncle, you are your own judge :P
