Here's what you need to know about how to read the new "Puzzle Stats" feature that I have added.
The checksum is the total of ALL the digits of the answer. So if your answer is 43° 20.876, -84° 30. 523 then you would add 4+3+2+0+8+7+6+8+4+3+0+5+2+3=55. I will occasionally give specific separate checksums for latitude and longitude when the puzzle warrants it.
Got it? Ask me questions in the comments and I will clarify anything that is difficult to understand.
