How Many Grandparents Do You Have?

A couple of days ago, I decided to figure out how many ancestors I have sucessfully identified- grandparents, great-grandparents, etc. As you know, we all have 2 parents, 4 grandparents, 8 great-grandparents and it continues to double with each generation. Here's a great visual representation:

I wanted to see how many of those I actually had and at what percentage was completed- giving me a good idea of what I could work on next. This is how it turned out: (Categories from left to right are: Relation, Name, Birth, Death, Age @ Death, Immigrant) Parents- 2/2= 100% Grandparents- 2/2= 100%
