I know expired is expired. But how much degradation would one expect from frozen Acros 100 expired in 2006?

If it was still within date when frozen I would expect almost zero degradation.

I would expect degredation to be little to none, unless it has been eposed to high heat, water, or repeated (>20 or so) Xray exposure, not including CT scanners, at some point in its life.

Most films will do OK at such a modest OOD. You should join those of us who use really old films from the 70s even ;)

I've had the same experience as Larry.

Slow to medium speed B&W film is pretty forgiving. I have some Plus-X that was found frozen in the bottom of a freezer at a local college that expired in 92. I got it home put it in my freezer and still shoot it to this day with no adjustment or worry of fog. It was a 200 foot roll.

ISO 100 or slower film is typically good for many years beyond the labeled date, as long as it's not roasted in a car trunk or otherwise abused.
ISO 400 film is a little pickier. Several years ago I found a long neglected bulk loader full of Tri-X, presumably left over from one of my kid's high school yearbook phase. As far as I know the film wasn't subjected to extended high heat in a car trunk. But it was foggy in Diafine, which I normally like for Tri-X. It was fine in ID-11, Microphen, HC-110 and other developers so I used it with those.

Well yes Lex that is why I sad Slow to medium speed I am from the old school where 400 is a fast film. I even notice a slight base fog with Diafine and newer Tri-X enough I can see the difference between Xtol and HC-110 compared to Diafine. I always thought of it as a little more shadow. :)

My film scanner is much too picky with expired TMAX 400, that likely got run through Heathrow's scanners a couple of times too before exposing it.
While I didn't notice the increased base fog after processing, the scanner sure did. Only then did I think to look if the film was expired.

Oddly enough, I've just bought 3 rolls of Acros from Jessops, the largest photography chain here in the UK. When I got them home I found that 2 rolls were dated 2013 but the third roll was dated 2008. It doesn't say a lot for their stock control.
