reddesert has it correct.
When I make notes about development for a roll of film, I just note the EI I used, the developer I used, and the developer number I used.
Sometimes I even refer to the development number in a post here on Photrio.
Here is a scan off an older, 1970 version which shows the table of Development numbers and the related instructions. I didn't post this one earlier because it is more difficult to use the dial when working in degrees Celcius.
The "white-on-black" Dymo tape additions are from a previous owner, who is unknown to me. I like the fact that they may be 50 years old!
These older versions are slightly smaller overall, and it is therefore easier to scan two pages at once
