I just found this link: Adox reciprocity post on flickr and the gentleman provides this excerpt from the main dealer in Germany:
"Dear Mr David,
we're happy that you like Adox film. I don't have a proper chart here, but they exhibit very little reciprocity failure. The rule of thumb is as follows (measured time and the factor of correction):
1/2 Sek. no correction
1 Sek. plus 1/6
10 Sek. plus 1/3
100 Sek plus 2/3
How does this information measure up with anyone's experience?
