Just a quick question, have been wonder for a while why there sometimes are differentiated between the course between Navigraph-maps and skyvector-maps or will this have something to do with cycle / date or magnetic deviations :-). Just an example below but have seen this many places. (often just 1 or 2-3 degree in diff).

Navigraph → LATINA 111.2 LAT 49 -à Z803 course says 097
Skyvector → LATINA 111.2 LAT 49 -à Z803 course says 096
Appreciates any feedback or tips , Thanks In Advanced
