Drifting compitition points system?

[Cloudedone]

Hey just wondering, in drifting compititions, how to they give points on the drifts? i know its Drift enty, Drift Exit, Car Style, Control of drift, and the amount of Smoke. (at least thats what i've read about the comp in hawawi and japan) its it like a score from 1-10 on each catagory?

BTW, anyone in northern CA be interested in one? I like in eureka, but sana rosa isn't too far, or SF for that matter.
