Yes, I guess you did, but you don't seem to understand that a correlation of US Overture with Simplified Chinese Traffic is going to give you no clue whatsoever as to the potential earnings of Traditional Chinese Traffic. The level of browser support in the PRC is much higher than in Taiwan, but exact levels of each are unknown, so you have no basis whatsoever for correlation.
I somehow doubt also whether you have a accurate measure of PRC based traffic. This is very difficult, unless you have PRC based hosting. The type in on Namedrive, Sedo and others is nearly purely US Type-in.
