Hi Ubydul,
under certain assumptions that might be correct; you have given us very
little information so you must make your own assumptions (e.g., is it
reasonable to assume that the number at risk of being a "case" was the
same each year?); note that (1) there should be no space between level
and the open parenthesis and (2) since 95 is the default, there is no
need for this option at all unless you want a different value
