Which fields have to be the same for something to be considered a duplicate?

How much leeway should there be in testing? For example if the delay for one is 1 millisecond and the delay for another is (1 millisecond plus 1 nanosecond) then should those be considered duplicates?

[groupnum, group_content] = findgroups(app.YourGUITable.Data.Period);
if numel(groupnum) == height(app.YourGUITTable.Data)
    %there were no duplicates
else
    for G = 1 : max(groupnum)
        mask = groupnum == G;
        if nnz(mask) > 1
            rows_that_are_duplicates = find(mask);
            content_that_is_duplicated = group_content{G};
            %at this point produce your popup saying that the rows in
            %rows_that_are_duplicates are duplicates of each other, with
            %each one containing the same content_that_is_duplicated
        end
    end
end

%several popups might have been generated by this point -- one for each
%distinct Period that is duplicated
