I really don't care anymore wheather I'm anoying to people here or not, so I'll just post my experiences with pushed E6 film in general.

What happens when pushing E6 is not a really linear process with steady consequences which increase whan you push more and more. What happens at one stop push is not always the same thing that happens at 3 stop push. Things can start to go into the oposite direction beyond a certain point.

One stop push is a mild thing, and you can't really observe much exept for some more contrast which maybe pushes the colors a bit with it.
Some films like Provia 400F can withstand 3 stop push and still look quite normal. But others start falling appart and only then do you see what is really going on when you are pushing:

-the Dmax is being reduced, which means that blacks are not so black any more, "smokey/milky blacks" is the term I believe around here. This happens because the more you underexpose, the closer you are to the films natural fog level.
-The dark parts get a color cast, usually a blueish cast. Though I've seen pushed slides with a warm cast too. Depends on the film. All this is because the yellow layer responds often differently to pushing that the other two layers.
-the contrast of the image itself is increased, but that is often somewhat compensated by the loss od Dmax
-the colors often get desaturated, beyond 3 stops you can really see it.

Process E-6 Push Processing:

http://www.kodak.com...14.3.30.3&lc=en (See Page 13)

PUSH/PULL PROCESSING
To obtain the best quality from KODAK EKTACHROME,
PROFESSIONAL EKTACHROME, and ELITE Chrome
Films, expose the films at their rated speed and process them
normally. You can modify the first-developer time or
temperature to compensate for underexposure by up to
3 stops or overexposure by up to 2 stops.
Compensating for underexposure will result in higher film
contrast and lower D-max, and a color-balance shift is
possible. Time and temperature adjustments give
comparable results.
Compensating for overexposure will result in lower
contrast and a possible shift in color balance, especially in
highlights. Time adjustments tend to produce less
degradation of highlights than temperature adjustments at all
levels of overexposure.
