In the family history sections, there are radio buttons for "siblings", "parents", and "grandparents".  How are each of these weighted compared with each other?  If I have two grandparents with the condition, would the "parents" button give the appropriate weight?  The example in mind is that both my grandmothers suffered with dementia in their final years.

I am just checking the grandparents box (once) whether I have 1,2,3, or 4 grandparents that had a condition.
