Anonymized EDNS Client Subnet is across the country from my IP

I tried enabling Anonymized EDNS Client Subnet, but it seems the subnet being used is across the country, which means any domains using ECS experience higher latency.

I used https://www.iplocation.net/ip-lookup for IP Geo lookups.

 

Based on that, my actual subnet resolves to Verizon FiOS in the NYC area.
 

However, the ECS subnet resolves to Washington state, which is all the way across the country from me.

    I get the same ECS subdomain when connecting from another location in NYC.

    My actual subnet again resolves to NYC.
