Now I hold the board against the ground post (or rather my lovely assistant does) and drill from the inside of the tunnel. This allows for a 'custom fit' of the bolt hole. If you simply measured and drilled, many of the holes will not match up because... well, things just aren't perfect. There's a goodly amount of variation in spacing and angle of the holes in the ground posts when you set them. This way that variation is taken into account.
