Another point, currently WD calculate the COI assuming the COI of common ancestors is 0 [Sum (1/2)^n1+n2+1], if you're using the complete formula introducing COI of common ancestors [Sum (1/2)^n1+n2+1 * (1+Fa)], you will see that calculating the COI with complete formula on 8 generations gives often a higher value than calculating the COI with troncated formula on full pedigree.
