Besides the exact GPS coordinate match and optional fuzzy match can be used via the -d/--fuzzy-cache argument. The default value is set to to 10m and can be set in the format number and m/km. Eg 100m, 1km During the run it calculates the distance from all previous cached entries and if one falls inside the given fuzzy distance this lookup data will be used and also stored in the direct GPS cache for further direct GPS matches
