Another clarification is that the statistic doesn't count the number of ward members with 100%, it counts the number of actual vs. potential ancestors.
In a hypothetical situation, suppose your ward has 5 members who qualify by age to be included in the report (turning 12 or older): Kilroy, Matthew, Mark, Luke, and Jill. The number of potential four-generation ancestors for each of them is 15 (1 self + 2 parents + 4 grandparents + 8 great-grandparents).
Kilroy's parents are actively involved in family history, and have filled in more than 4 generations, but Kilroy himself has not signed into FamilySearch to connect himself to the tree.
Last year, the calculation would have been done like this:
Kilroy has 15/15 ancestors filled in (because his parents have filled in at least three generations, and he's connected to his parents via Church membership record).
Matthew has 2/15 ancestors filled in.
Mark has 6/15 ancestors filled in.
Luke has 10/15 ancestors filled in.
Jill has 12/15 ancestors filled in.
The total number of four-generation ancestors filled in for your ward is 15 + 2 + 6 + 10 + 12, or 45.
The total number of possible four-generation ancestors for your ward is 15 + 15 + 15 + 15 + 15, or 75.
Your ward percentage would be 45 / 75, or 60%.
This year, the calculation would be done like this:
Kilroy has not connected himself to the tree, so he has 0/15 filled in.
Matthew has 2/15 ancestors filled in.
Mark has 6/15 ancestors filled in.
Luke has 10/15 ancestors filled in.
Jill has 12/15 ancestors filled in.
The total number of four-generation ancestors filled in for your ward is 0 + 2 + 6 + 10 + 12, or 30.
The total number of possible four-generation ancestors for your ward is 15 + 15 + 15 + 15 + 15, or 75.
Your ward percentage would be 30 / 75, or 40%.
Note that in this scenario, nobody has 100% of their four generations filled in, but your ward's statistic is still above 0% (because it's based on number of actual vs. potential ancestors, not number of members with 100%). (Chances are that in your real ward, several members have 100% of their four generations filled in, but there's no way to know that using the report.)
