You're welcome:0). Yes, it can be a bit disconcerting trying to figure out all the information available. With this spreadsheet, however, I believe the data is pretty accurate, well as accurate as these types of devices can be - the problem is -just as was mentioned - it does only give an average. I think most people will find, however, that if they have a parent that is chinese and one who is from south african, that both areas will probably show up on the map - their 'score' however, might be lower for these two areas, where as the score for India might be higher. Now, this is just my theory - I really do not know enough about it.
I was told however, that you can split the STR profile numbers (CODIS Markers) in half. For example, place the first four markers into the green cells on the spreadsheet, and print a copy of the world map results with only those four markers, then delete those four and put in the remaining CODIS Markers in thier appropriate green cell - print a copy of that map. Now compare the two maps for similiarities. You're looking for the areas on the map that have clusters of 10 to 15 blue/green/black dots. For example, in my case, the areas around Spain and Portugal remained the same on both maps.
I hope this helps.
