"My goal is to set a measurement or weight that will indicate how well the variable is differentiated in its values and isn't characterized of lets 70% or 80 % of the same value."
Are these not variables with platykurtic distributions?
Kurtosis - Wikipedia, the free encyclopedia
Kurtosis is calculated by many SAS procedures, the most efficient of which would be PROC HPDMDB.

"I have noticed many bugs and wrongs in Eminer computations" - like what? I am not only a developer for Enterprise Miner - I am also a certified Predictive Modeler for Enterprise Miner and I use it nearly everyday for very complex tasks. While I occasionally see things that I think are bugs, it's nearly always something I just don't understand. Enterprise Miner is tested for functionality and numerical validity year-round by a team of professional statisticians, data miners, programmers and testers all over the world. It is extremely unlikely that such a team could miss "many bugs and wrongs in Eminer computations". However, if you truly think there are problems, these need to be reported to SAS technical support immediately.
