First of all I have to agree that the plugin is poorly documented, far from intuitive and obsolete after all... I just have to say that initially my intentions were purely good. I wanted to make a tool that may help to model something more complicated than just a basic geometry. It was not intended to make anyone mad or frustrated. Vojo, please accept my apologies for having failed to meet expectations.

I.e. since power not documented, a user may try 1.0 thinking he gets a 1:1 movement (or at least see that the movement is some linear relationship between the control points...
Speaking specifically about the term "power" I must say I really was not aware about the fact it might be misinterpreted such a way. "Power" means literally "power" here in a mathematical sense (not a linear coefficient or a factor). Actually I gave some more or less explicit explanations here in this thread about how it all works earlier (about three years ago):

The second method calculates offset vectors lengths of each vertex according to distances from it to all control points. The degree of influence of each control c-point depends on <1/(distance^power)>. Power is an adjustable value.

In other words algorithm utilizes a type of deterministic method for multivariate interpolation with a known scattered set of points which is known as "inverse distance weighting" (IDW): http://en.wikipedia.org/wiki/Inverse_distance_weighting
Plugin interpolates offset value (support of rotation and scale transformations were also added later).
Anyway I highly recommend to stop discussion at this point, because discussion of an obsolete plugin is a kind of pointless to my mind.
Everyone else who was confused please also accept my apologies for not informing about the fact that this plugin has become obsolete at a time.
