Time difference between Kurviger and Google Map

Hello Kurviger Folk

I created a route with Kurviger and then did the same with Google Map.
I’m surprised at the difference in calculated time.
The distance is the same for both, but for a route of 217 km I have a difference of almost 30 minutes more for Kurviger.
Is there a setting I forgot to put in?

Thanks in advance and good curves!

When it comes to ETAs Google has a lot of statistical data and knows exactly how long users usually take on a certain road and what the traffic is like.

So it can happen that there are differences in the ETA.
