I'm not sure what conclusions you think we should draw from that. California's advantage over Washington is primarily one of size - Washington's GDP per capita is actually about 3% higher than California's. The most generous interpretation I can think of is that you're crediting the non-compete difference for California's far larger population, which is tenuous at best.
Seattles weather does nothing to lower the denominator. The PNW is rainy and somewhat cold, but not cold enough to kill homeless on the street in large numbers which is what folks seem to think lowers the denominator. And yes I do live in the PNW.
