Andy, Tom, Nick and all,
I support Tom's suggestion. 

I would also like to suggest one more extension to the survey.

In its present form, it says how many *operators* can use CW in this or that PW type where it is optional, and how many *operators* actually use it - again, per PW type. It also says how many PWs of this or that type have been actually deployed.

IMHO and FWIW, it would be most helpful if we could have the information about the number of *PW instances* that use (or do not use) an optional  CW - again, per PW type.


Regards,
     Sasha
