I believe the saying goes "You can test blow yourself right out of =
business!"

  I think the general way stability is taught is backwards:  i.e., tune =
soft
  and test with a few hard blow.  For the best stability I think you =
should
  tune with hard blows and then test soft where you can hear (or read) =
small
  deviations.
