I've been investigating the event record data issues again.  The design
document at the URL above is now much more detailed and I think captures
the scope of all the work needed (as far as I understand it, ahead of

Now would be a good time for feedback if you have any.

I think the execution of these changes is a bit messy rather than hard.

Cheers, Ken.
