Hello Christian,
main key parameter for guidance that influence "when" Locus switch to next trackpoint is "Set next trackpoint" (in Guidance settings).
My expectations were wrong because i always looked for a setting like "set distance for notification".
Now i understand how the next notification is computed by Locus.
The distance is not calculated for the related upcoming waypoint but for the trackpoint located after the waypoint.
And... the calculated distance is beeline.
That means if the trackpoint behind the waypoint is behind a turn with >=90ยบ (in most cases) the real distance becomes smaller. Thats why i get notifications in different distances and time intervals. Sometimes its quite short for leading the peloton around the corners when the computed distance is not equal to the distance to go by bike. So the notifications are not really reliable.
Is there any chance to improve this small system a little bit?
