While Live segments do not trigger regularly, each time it works I receive an immediate "Off Course" Message simultaneously with the end of most (each?) live segment.
Further, the segment times shown on Strava are much worse than the ones displayed, usually 7-10 seconds, topping at 12 seconds, lower; independent on the length of the segment.
While I understand that there is a different algorithm used by Strava to compute segment times, in the past I was used to a 2 or 3 seconds penalty and no "Off course" messages.
I use 1 second GPS intervals and GPS+Galileo.
The problem might have appeared with the new route sync method for Strava routes, yet I am not sure if I had those issues even before that.
Do other people also have these issues? Is there a solution?
