Is all this about chains true?

Of course most speedos over-read a bit, were you to change the gearing in the appropriate direction the speedo may become more accurate.

Im confused, I thought that the speedo sensor was on the front wheel, so given the diameter of the front wheel is not changing how does the size/rotation of the sprocket affect it?
