They mainly differ on what they include and how they present it. WoW and for the most part, DVE, pretty much hold your hand and walk you through the whole process. Spears & Munsil assumes, more or less, that you know what you are doing and just gives you the patterns, clips and sample videos. No one tells you what you need to do or why. There is, however, a brief narrative or help if you push up on your blu ray player.
The big thing I hated most about the original DVE was navigating through the fluff to get to the meat. WoW isn't too bad but I don't recall if they include any decent content to check your adjustments. I know they include some animated stuff but that isn't what you want for checking white and black levels.
The other thing you should consider, regarding your numbers, is that you are introducing at least one other variable to the equation that cnet doesn't - your blu ray player. And maybe your receiver as well. Both of those may have an effect upon the end image as well. I haven't seen where you got the settings from at cnet, but if they were from David Katzmeier, he probably uses a video generator to calibrate and produce his settings.
Lots of variables to think about.
