Let me start by saying, I have no food science degree. I have only 3 yrs experience as a QA Manager. Prior to that 4 yrs as a QC Tech. We have passed numerous 2nd and 3rd party audits since my being the QA Manager, 5 audits in a span of 1 1/2 months at one point, including clients, BRC, and a FSIS FSA (2 NR's, only minor, paperwork, and I never want to see that guy again!), all passed.
We call it chill/freeze because chilling as well as freezing meets the USDA requirements for time/temperature requirements for cooling. No-one has ever questioned the fact that the freezer is not a CCP.
Our Chill/Freeze CCP follows the USDA Time/Temperature Guidelines. Temperature does not remain between 130°F and 80°F for more than 1.5 hours nor between 80°F and 40°F for more than 5 hours.
We use the nitrogen freeze tunnel as our process according to Federal Code of Regulations Part 430.4 Alternate 2. to supress or limit the growth of L.m.

To mention a few of the resourses and scientific data we use to justify our process.
GMP's, sanitation, etc.
If I'm not answering correctly, what your're asking, that's because I don't understand the question sometimes, but I do understand why we do things the way we do, and thankfully the auditor's understand, that I know the who, what, where, when, why and how of things. Just in a laymans terms
Believe me, if I had the funds to pay for further food science education, I would be first in line to sign up!
