Find my Mac test results off by a half a block
iPad, iOS 6.1.2
How good the position can be determined will depend on the location of the nearest Wi-Fi spot or if GPS is available.

Does your iPad have GPS? For me, the "Find My Mac" position is always very precise. I can even tell the room I'm in, if the iPad is close to a window.
Most likely atmospheric or an issue with triangulation of your position. There's nothing to worry about, it won't be your devices fault. It happens to me quite a lot. Even when all my devices are grouped together. One can look as though it has gone for a walk, by itself...
I have an MBP and an iPad 3, both of which show as being close to but not on the money - across the street or in the street. No GPS on either. No problem now, but if one were to be stolen or lost, I couldn't be sure just where it was... just the general area.
Is there any way to tighten the thing?
Nope, unfortunately, you are at the mercy of the mobile broadcast towers and network speed/accuracy.
