I just recently bought an NEC P221 monitor the other week and am overall pretty happy with it. I just purchased the spectraviewII software online and ran some tests. I share an office with another photographer and we both have gretag macbeth eye 1 display 2 pucks. I was curious to see how each puck calibrated the monitor using the spectraview software. With that said, the pucks give a very different contrast ratio and delta E value, from looking at the attached summaries, does it look like one of the pucks is broken or more accurate?

It's not uncommon for a profiling result to end with luminance values that are different than your aim. Your puck # 1 at 134 came in under your aim of 140 and puck #2 was 141. These differences in luminance might affect a lot of things. The brightness of a display affects color perception more than many people think. I don't believe that by itself is responsible for your higher delta E values for puck #1 though.
Have you run the pucks through the i1Diagnostic program yet? X-Rite has a free download of a diagnostic program that you can plug an i1 device into, and it will run it through its paces & give you some numbers & tell you if it passes. This is not always a guarantee that things are okay, but it's helpful.

To my eye they both look odd - all P221W I had calibrated (about 6-7?) had R,B colorants pretty close to AdobeRGB R,B colorants.
I suppose it's a general problem with an i1 colorimetrer, that doesn't work well with wide-gamut panels.
Check "Factory measurements" in Edit>Preferences>ICC Profile>Source of primary color chromaticities for ICC Profile. It would also be perfect to calibrate the panel with i1pro, ColorMunki spectrophotometer, or custom NEC colorimeter.
