It's not 'incorrect' -- clearly the flat trend has existed long enough for this 'spike' to represent something other than random noise. Would you say that the dips on weekends are 'random noise'? No, they too represent a trend, though if we zoom out far enough they would get lost in the lack of precision.

Flagged as incorrect.
