Where can I find Winter pooling statistics for each Cambridge college?

I have been trying to gauge Cambridge college choices by difficulty, and want to be rest assured that I can trust the winter pooling process when applying to a college.
For example, the computer science admission statistics for 2022 show that 320 students applied for computer science at Churchill and only 15 offers were made, due to its popularity. Whilst Cambridge's official statistics website shows how many of those offers were made by the winter pool, it doesn't show how many applicants to a college were winter pooled by their respective college.
Ideally, in a perfect scenario, the sum of the pooled applicants, and direct offers in proportion to the number of applicants should be around the same for every college.
Sorry if this question has been asked around a lot, and thank you in advance!
