But genetically dravidians and other south indians are about 60-70% caucasoid, and the rest is proto asian(australoid), so they are mixed, north/west indians are around 80-90% caucasoid.

Well Western Eurasian admixture in both central asians and south asians may have been bit overestimated in many previous studies. I would say for now, it is somewhat safer to say that south indians are about 50 to 60% caucasoid and northwest indians are around 70 to 80% caucasoid(at least going by David Reich's studies).
