94% 10 miles 292 sec
Fun but not very scientific or indicitive of intelegence or knowlege of the states
It all depends on what states you draw to start with
If you start off with MO, CO, or UT in the begining it is tough to place them exact without a reference
If you get border or coastal states to build from it goes faster and more easy.
Luck of the draw, but anything above 90% should be average
Anything less your a primate putting square blocks in round holes with a hammer
Who misses Hawaii by and average of 11 miles anyway
