I'm not saying you should tune at test blow level, I'm saying you should =
tune with hard blows.  They also teach that at the S&S C&A dpt.  Not =
surprisingly, it works.

    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.
