PNA SMOOTHING ISSUES

Can anyone (Dr Joel?) explain to me why it is that the PNA distorts the phase response by reducing the max phase angle excursion when smoothing is envoked?  The 8720 series and 8510 VNAs don't distort the phase like this.

When is Agilent going to fix this?

I need to do some smoothing on the phase to reduce the noise on the data. Averaging helps some to reduce the noise, without distorting the phase, but not enough without seriously impacting test times.

Alternately can anybody point me to some code (preferably VEE) that I could use to do post processing smoothing without tweaking the phase?
