I was complaining about this earlier this summer (http://www.steinberg.net/forums/viewtopic.php?f=194&t=62189 see the bottom of page one) and NOBODY seemed the slightest bit concerned about this. There is no version of Eucon 3.x and above where the readings matched. When I asked why this was I was told it didn’t make any difference because the offset was so small. But, to me, if it doesn’t match, then its not right.
As Eucon is now a PT device, it is highly unlikely that this will EVER be corrected. So, I don’t bother using any of the knobs on my MC Control, they’re inaccurate and slow. The trackball is much faster and more efficient!
