So you're saying they measured every single curve and bend and it comes out to 11,165 miles but since it curves and bends it is a lot smaller geographically due to the scrunched upness?
That is a good explanation I'll give you that but what is the diameter of Antarctica? How many miles wide is Antarctica from coast to coast.
Here's something I noticed while on the wikipedia page that is interesting. It says that Antarctica is made up 44% of Ice shelf (floating ice front), 38% Ice walls (resting on ground), 13% Ice stream/outlet glacier (ice front or ice wall), and 5% rock. So basically it is made up of one big Ice Wall all the way around.
But even if Antarctica was "scruntched up' a little bit, the "scruntches" don't go very far back into the mass so I would assume the difference in circumference would not vary 7000+ miles.
