Thanks very much for the quick analysis!

I apologize for letting this slip. Junmei has been out of email contact for a
while (I suspect some emails may have been going to a mailbox he is no longer
reading), and I've swamped with travel. But we do have your emails archived,
and I will try to address the problems you raise as soon as I can.
I agree about the need for a suite of molecules to serve as test cases. If
you (or anyone else reading this) has a good suggestion for implementing this,
I'm willing to help with the Amber part.
Again, I apologize for the delays in dealing with mail-list posts about
