RE: New Proposal - Measurement (in support of describing sports statistics)

My latest thinking:  

Measurement, in its noun form, consists of a quantitative value which was assigned to a quantity representing a property of the direct object of the Measurement action.  In addition, Measurement, in noun form, consists of a bunch of other meta data associated with the performed act of Measurement, such as when the measurement took place, how long it took, what instruments were used, what conditions were in place at the time of the measurement, etc.

A Quantitative Value (Quantity Value / Quantity) is simply a number and a unit of measurement.  That's it. 

If you want to capture just a number and unit, use a Quantitative Value.
If you want to capture the semantics of how that Quantitative Value was established, use a Measurement.

As defined in VIM and O&M, and reflected in the current schema.org proposal, these are quite different things. 
'Measurement' is an action or event, the _result_of_which_ is a quantitative value.

Conceptually, I think there is no relevant difference between a quantitative value and a measurement, since all what we process in computer systems are abstractions of reality, so any qualitative value represented in any computer system is essentially tied to a measurement activitity (except for values generated randomly or algorithmically, but with a wider notion of what "measurement" means, that could well be covered, too).
