Some of their documentation / promotional material is unclear on this point, IMHO. The V1 Decent tamper has a calibrated spring as you note, but it is not a leveling tamper. The V2 Decent tamper is a leveling tamper, but its spring is not
pressure calibrated. There has been some discussion on the Decent Diaspora recently of why this is. John Buckman claims that, contrary to some of the views expressed in this thread, recent research shows that tamp pressure beyond 10lbs makes no difference to the shot, unless perhaps you try a Herculean tamp of tons of pressure. According to the research he quotes, leveling is the key variable, hence the V2.
