◆ tared_reading()

double anonymous_namespace{test_lc_linear_fit.cpp}::tared_reading ( const CubicFit & f,
double zero_code,

The scenario.

A tank is on the scale; the scale's zero has drifted from 400k to 200k overnight (the whole curve slid 200k counts down; the sensitivity did not change). The operator tares with nothing on it, then puts the tank on. What reads?
