HI Hugo et al.,

I think the details of how the distortions are derived and combined (hence 
the flow chart -- probably a 
'rev 3', with the 'validate' step fleshed out) would be good to show, along 
with the status of the components.  This matches a lot of Hugo's comments. 
Some of the details of the central membrane distortion monitoring (which we 
will discuss tomorrow, and hopefully have a pull request before the collab 
meeting) have also progressed since last time.

I would be glad to assemble the slides and present the status.

-Ross
