At the moment, 15% (1:6.8) are in the UTC+2:00 timezone, which covers most of mainland Europe using Daylight Saving Time.

Sounds ballpark reasonable to me - Europe is twice the population of USA, and USA is split over more timezones. And Asia has more people than USA and Europe put together.

In my case, Safari on iPad makes me 1:67,000. Chrome on the same iPad makes me 1:1.6 million.
