To be frank, I don't understand this stance. As I see this type of
issue, either you have independent reasons to believe that the patch is
beneficial and just go ahead, or you should repeat the test enough times
and in the correct conditions until you reach statistical significance.
Otherwise, I don't believe it really makes sense to mention numbers
which you don't trust yourself...
