Soft blows

I got more like 1.5 lbs from the tension spike, assuming the 0.049 (???) 
deflection at an (unspecified) 1/8 strike point  on a (unspecified) 408mm 
(unspecified) 440 Hz string. If this comes with any actual specifications 
that differ from my assumptions, I'll re-figure.

But not knowing what the tension differential between the speaking length 
(and beyond) and the rear duplex (and beyond), the information is pretty 
much useless for determining whether a hard blow will pull a string through 
the bridge pins.
