Interpreting the linebreeding section - Page 1

I could use a little help specifically interpreting the linebreeding "inbreeding coefficient" section. I understand what all the pieces (e.g. 4-5, 2-3) mean and how the individual values are being calculated on an ancestor, but if I want the total, one number COI for a particular dog, do I add up each individual Hardiman's COI percentage?

So, for example, if I had a dog who had a line breeding section that looked like this:

5-4 [insert bitch here] - 00.44% - 05.86%
4,4-5 [insert dog here] - 00.44% - 07.03%
5-4 [insert dog here] - 00.39% - 02.93%

Would my Wright's COI be: (.44 + .44 + .39) = 1.27
And my Hardiman's COI then be: (5.86 + 7.03 + 2.93) = 15.82

Thanks in advance, I really appreciate the help!
