Creating a deviation table from a GPS.

Coming home last weekend I had to steer 280 degrees magnetic to maintain a "GPS heading" of 275. Should I look at that and conclude that my compass has a 5 degree error?

GPSs don''t know much about compass directions, they only know where they are and where they were.
