The stress patterns exhibited by the test are identical to others in
BAT. The accuracy tests are covered by others in BAT. The actual flow
(edge coverage) will be subtly different and therefore the test is still
unique and may catch future bugs not caught by others. But as far as BAT
goes the likelihood of this catching something not caught by others
within BAT is very very small.
