There are multiple meanings of the word "error". I just don't care how accurate that the watch is (thus far anyway) because the perception of progress—delusional or no—is why I use it. Generally, though, my perceived performance is reflected in the relative numbers. If I felt otherwise I too would be complaining about accuracy.
