How did you actually do in the past with document film?
Originally it was intended as a microfilm that was developed to a high contrast, it was never intended be a pictorial camera film. Thus the need for special developers that can lower the contrast to bring it into the pictorial range.
Typos tweaked.
Beverly Hills, wow only EI 25 in your case for Ilford and down to 6 with overexposure and pull development
If it's only 25 for you and that works for you then fine there's no more to be said but it just sees very low given that Greg Davis in his video about it confirmed that in D76 it was a genuine 80 speed film and from what I recall from others none had it as low as 25 of even mentioned that it was not a box speed fim

Just from my mind, how does it work if you shoot with overexposure and pull development - the contrasts become
weaker ?
Thank you, i've no doubt : ADOX ADOTECH ist a great developer, with best results.Only to a point. A high contrast developer doesn't be come a low contrast developer simply by diluting it, you need different chemical reactions to produce satisfactory results.
Inn the case of the Adox CMS-20, every test I have seen shows that the dedicated Adox developer does produce the best results. See the video Andrew made:

Ok Craig i've alreadyOriginally it was intended as a microfilm that was developed to a high contrast, it was never intended be a pictorial camera film. Thus the need for special developers that can lower the contrast to bring it into the pictorial range.
In this case the Ilford would have the same speed as the Rollei,
are you sure about this pentaxuser?
Not a problem for me, but still a bit strange.
Yes of course, thanks.Have you considered using XTOL?

thanks, I only can say that I remember a similar issue withI have never used Ilford Ortho 80 but as far as I can recall the general consensus amongst its users was that it is a genuine 80 speed film. Does the 25 in the Rollei Ortho not indicate that the 2 film speeds are not the same? If the box speeds genuinely differ then why would Ilford and Rollei not differ even if your EI speeds for both are not the box speeds
For what it is worth Greg Davis in his tests on both films seemed to confirm that Ilford was 80 and Rollei was 25
