Inharmonicity measurements

Hello all.

In my effort to understand clearly the scaling problems, I would like to =
be able to measure the real inharmonicity of a real string in a real =
piano (that is : not guessing it following a theoretical model formula).
I own a Verituner and would like to check if I understood things right.
Is it so, that with the Verituner, when you disable all "style" extra =
stretchings, you get the actual reading for all harmonics on the A4 note =
relative to it's fundamental ?  If I got it right, all other notes are =
not actual readings, but so called targets, that is ideal values which =
you should reach by tuning their fundamental with an offset compared to =
their theoretical value.
If I understand that when the Verituner reads, in fine mode,  for A3=20
1 : -3.49
2 : -2.34
3 : -0.74
4 : +0.98
etc.
it means that the fundamental of A3 should be tuned 3.49 cents lower =
than it's theoretical value in order to achieve the best tuning (best =
compromized matching between all partials), I'm not sure though what 2 : =
-2.34 really means.  Does it mean that, reported to the actual value of =
the fundamental frequency of A3 when well tuned following the verituner =
algorithm, the second partial is actually -2.34 - (-3.49) =3D +1.15 =
cents above it's theoretical value (which is simply the double of the =
frequency of the fundamental) ?  Or is it a target again ?

Thanks for enlighting.

Best regards.
