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.
