Vladimir Galogaza was kind enough to fully translate this page for me.  I have the full translation of the text and will send it to anyone that asks for it.

The following snippet is the web page author's summary, as translated by Vladimir:

---------------------------------------
Facit:  [conclusion, summary]

I have compared accuracy statements of several software producers, including also 
a [?] program "Intelli.Wave" .  All producers give approximately same accuracy for interferometric analysis. It looks like with interferometry with one fold accuracy of interferogram
there is no warranty for better than lambda/30 surface ( lambda/15 wavefront) accuracy.
Independent from additional errors introduced by testing procedure and others.

This corresponds to a wavefront deformation of about 45 nm for measurements with He-Ne laser. Results in this work are all within usual limits. Even the big P-V value difference in the last test is still in normal range.

After performed test we can really be happy with this program.  We hope also that correct use of the program was explained.

Such program is very good thing, but there should not be an impression that everybody that down loads this program from Internet, can in few minutes with 100% accuracy analyze an interferogram. It takes a lot of background knowledge and experience.
