"I got my EyeOne Pro Rev B recently too, and noticed right away the higher
positioning of the spectro's head above the paper, compared to the previous
version of the ruler.
I get reliable and consistent readings most of the time with the new ruler,
which I have put through several rounds of testing to reassure myself that
it performs to my satisfaction.
But I would like to introduce another consideration here:
My room is not usually very bright; the rainy weather in the SF Bay Area has
added to the darkness lately. But I noticed one day the other week, when it
was nice and very sunny outside, with bright sunlight coming in through the
window, that I was getting some wildly variable readings from one
measurement session to the next on some of the patches in a printed
1780-patch ECI2002CMYK testchart. A few patches (usually darker ones, some
of them green) jumped around from one reading to the next to the tune of 18
Delta E 2000, even! (I calculated those Delta E values by comparing
measurement sessions with the Comparing tool in MeasureTool)."

Have you tried doing a reading comparison using the small spot reading tool
that accompanies the i1. This tool positions the spectro head at the old
"dark" position. This should answer any queries you may have about the old
and new head height.
