Wrong distance during hiking

Hello,

I did two hikes today and yesterday and I noticed the distance was too much on Venu 3 compared to a forerunner 245. More precisely the distance was 1km too long on the two hikes which were around 10 km. After checking the forerunner is right.

On the two watches, auto-pause is disabled and smart recording is used.

Venu seems to have a gps drift while standing still. Maybe I should use auto-pause setting but it doesn't exist on hiking activity, and I don't use it on Forerunner anyway (with walking activity).
