Does Elite offer simple, less specific choices as well as the more 
specific, more technical choices you mention? The reviews with screen 
shots of the set-up process appear to include such options ("Elite 
allows you to specify your own luminance level, by candela value, 
instead of the simplified numberless version in Pro.") 

BTW, I had previously scrutinized the chart comparing Pro and Elite - 
the chart lists the differences, but does not explain why you would 
choose one over the other, why that difference matters, or how the 
different options would impact the calibration process.

Thanks
