Why not start with a nit?

Have you ever noticed that online maps don't usually point to the right house/business on a street? I was looking at one today and noticed that google maps pointed to the wrong house. The addresses on my side of the street go from 1 to 13, and my address is 11 so I am near the north end of the block. But google pointed to the south end of the block. I suspect that they assume the block goes 1 to 99, and place the pointer at 11% up the block for an address that ends in "11". They should look at the highest number on the block and divide by that instead. Just a nit, but Google could do it...
