Oooh yeah, that was nicely said.
I would definitely want to respond to that information sooner than later (the six weeks til the update) and if it were me sending an email like that (no matter what the motivation) I would hope for a response sooner as well.
Perhaps after what CJ said toss in one sentence (maybe you can commission her to write it?
) mentioning the quarterly update in about six weeks to put back in place that boundary of when updates/contact occurs. Just a thought....
ETA: By sooner than later I think next week is fine
