If you look at each image and assess the amount of drak tones vs light tones in each image, you may be able to see a pattern in what your meter is doing. I would expect the images with the largest amount of drak tones and the least light tones to be the ones where the overexposure of skin is the worst. Any number of articles on how matrix metering works to explain this one.
Some specific suggestions -
Firstly are you shooting Raw or Jpeg? There'll be a huge contrast range in your subjects and Raw would definitely help, you'll have 12 or 14 bits rather than 8 bits per channel to play with.
Secondly as you found later in the session, spot metering off the skin would help (or exposure lock).
Thirdly, check the histograms.
Fourthly, bracket!
Now out of ideas, hope some of this helped....

- once you fit it you can't see anything through the viewfinder, so you need to use the camera on a tripod (which you'll need anyway, since the exposure times are so great) frame the shot and then fit the filter.
- the filter lets in so little light that the autofocus won't get a lock, so focus with the filter off, fit the filter, switch to manual focus and don't touch the focus ring!
- the meter may or may not give a sensible reading so be prepared to switch to manual mode and check the histogram
- most "big stopper" filters have a colour cast, so shoot RAW and you'll have more room to play around when you correct in post processing.
I'm sure others will have more to contribute.
I'll post an example image from the other day in the gallery.
Cheers

I'm sure other forum members would be keen to see images, so keep us posted and good luck!

I'll stick one of the pics in my gallery (this one will also be the guidebook front cover shot).

Haig mount is powered via a stepper motor needs 12v, if car is nearby then I can run an LV extension lead and go off the car battery.
