"Efficient XML Interchange Measurements" draft made public

http://www.w3.org/TR/2006/WD-exi-measurements-20060718/

The conclusion is "At the time of writing of this first draft, it is too 
early to give conclusions drawn from the test results. This draft Note 
is being published to encourage review and comment as this work 
continues."  I see the results of a lot of hard work, and that work 
seems to be accomplishing some of the unfinished business of the old 
Binary XML Characterization WG. Still,  I don't see anything to 
disconfirm my a priori belief that it will be somewhere between 
difficult and impossible to to develop a Binary XML format that covers a 
wide range of use cases and yields a useful degree of compression and 
speedup (and all the other properties).

So what am I missing?  Is there a bunch of result data that I'm just not 
finding a pointer to?   I realize this effort isn't complete, but what 
evidence can be gleaned from this to support an argument that the EXI WG 
is on track to discover or produce a spec that will meet its objectives 
spelled out in http://www.w3.org/2005/09/exi-charter-final.html ? 
Specifically, they are supposed to be 6 months from a Last Call working 
draft  of a standard EXI format; does anyone think that is likely to happen?
