A 6 electrode 180 Hz firing rate has always been looked at as likely the
worst of all cases. Haven't tried it myself, but there is an old DOS
program (1991) by Robert Jamison you might want to run that looks at
various configurations, and yes, the 6 electrode case is there. It's a
simple .exe file. It's at my web site if you want to download and run.
