why does route shows less distance when converted to track

[howard40uk]

my walk showed i had done 10.4 miles but when converted to track the distance went down to 9.7 miles .why is this ?

thanks howard

It is my understanding that the conversion filters out some of the data and removes some of the general GPS wanderings.
