Are you talking about 200 runs with 8.2.4 or 8.3? If you've collected a
bunch of 8.3 data, that's something I haven't been able to do; if what
you're saying is that you never found settings with 8.2.4 that you'd
recommend, that's consistant with what I was saying.

Am in the middle of wrapping this up today, will send out a patch for
everyone to try shortly. Tests are done, patch is done for now, just
writing the results up and making my tests reproducible. I had some
unexpected inspiration the other day that dragged things out, but with
useful improvements.
