I've been reading all the notes on WFD fixes, but so far I've been
(uncharacteristically?) silent. Anyway, I want to take advantage of a rare
opportunity to agree with Doug.
Erik has done a very good job thinking through various aspects of
the fixes and keeping people informed about them. I think now, along with
Doug, that it's time to pick one of the approaches and implement it. We
need to fix _most_ of the problem now and worry about the last 10% later.
I haven't been to the lab for a while and am not as involved in the
WFD as I was in the past, but I do think that the solutions aimed at
reducing the overshoot by adjusting the coupling seem like the most
straightforward. From Erik's earlier messages, it sounded like this was
going to be done first, but now I've been confused by a lot of stuff
regarding the new trigger. Is the plan still to redo the coupling in an
entire supermodule? If so, it seems like that should go ahead while we
continue to discuss the possibility of a new trigger, with the mind that
the issue should be resolved in the next week or so.
Just to put in my own two cents, I would _really_ like to fix this
without adding a new layer to the onion. Do we have enough hard data on
the direct overshoot fix to insure that it won't work well enough?
