Are you planning to add a regression test? Or you think this is too
much of a one-off regression? Just curious.. 

Hmm, I didn't plan to write a test case for this corner issue. But with your
reminder, may be I can add a common updealy/downdelay parameter test case.
I will add this on my todo list.

Thanks
