you can be in California and using say an iPhoneX and it will tell you you're one in 500k. If you calculate the number of people with their iPhone set to English in the PST timezone (the only things there is to distinguish one iPhoneX from another) and then you divide that by the pantoptclick number you get it's claiming there are only 10-100 iPhoneXs in all of Seattle Metro Area, San Francisco Bay Area, Los Angeles Metro Area, and San Diego Metro Area combined. Clearly wrong
