Darling, im impressive without false accolades. I identified the flaw in your numbers, formulated the fix, did the research and posted the results in about 2 min. That seems pretty impressive ;)
as for the elders hearing these things and being affected.. I served 10 years and never heard a case of child molestation. There were never any REPORTED in my congregation, not to suggest they didnt occur.
The only reasonable way to extrapolate would to be do it by country stats. Number of cases per 1000 of child sexual abuse in a given country then reduced it out to the same ratio per 1000 of jw in the same country. That allows for normalization of given societal norms in the statistical compilations.
