Well if you want to understand what it means then you need to know what 
the calculation is behind what awstat is doing! In this case I assume 
that it is telling you the number of unique IP addresses if there is no 
tracking cookie but that is a very poor approximation for the a number 
of visitors.

Plus you asked about unique visitors to the tile server but now you want 
to know about unique visitors to our slippy map, which is an entirely 
different question as not everybody that uses our tile server uses our 
slippy map.

Every question seems reasonable to the person asking it, but as always 
the question is where to draw the line - do I have to conjure up 
whatever statistics people ask for no matter how much work it needs?

Anyway, if you can get the appropriate people to authorise it, and you 
can clarify exactly what you want, then we might be able to do something 
when we get a minute.
