That is about 7% low, very strange. Looks as if your tyre is larger than expected. The circumference should be 1840mm. You could simply measure the real value.
The speed sensor gives 4 ticks per rotation. Any failure, or wrong sensor type, would give a much larger deviation.
Last thing I could think of would be that the speed signals are electrically marginal and a few get lost from time to time.
