Thanks for the quick answer, I have chosen typical in the car, but the watch shows estimated (big enough to read) and very small the typical. I´d like to swap these to.
I have a question regarding the app on the Apple Watch with Watch OS3: Where can I choose, which range is displayed, I would prefer typical over the displayed estimated.
