@f09fa681 that's like saying "I know I rolled a 4 on my d6 so the probability of rolling 4 on a d6 is surely higher than 1/6th."
What you're missing here is that your personal distance to nearest Cloudflare datacenter is not the same thing as the capture area of that datacenter.
If I only have your closest Cloudflare DC to go on to figure out where you are, that area is much, much bigger, than the area I have to consider if I have your IP address.
