DA and bolt torque instead of tuner

Beeing a 3P rifle shooter I have followed the tuner discussion closely. In stead of using a tuner we position shooters have to 'play' with the torque of the bedding bolts. This led met to testing several types and speeds of ammo under different DA situations. I came to the following conclusion (with my rifle, a Walther GX-1):
for every 2m/s velocity increase bolt torque goes up by 0.01Nm
and
for every 750m DA increase, bolt torque goes down by 0.01Nm

Any comments apreciated.
