Toby,
I have the same feeling as yours.

  I am not convinced that prediction is quite right. To me it implies a particular approach (namely re-ECN) and I am keen that any WG is given the freedom to eventually explore other possible approaches.

  Having said that I am also not completely convinced by "expose" or "Exposure" (preferring instead transparency with its associated economic context). However, as Bob said in an earlier email we seem to have converged that as being the word that causes least confusion.

  Sadly whatever you choose to call something is always open to misinterpretation...
