I did do, in the run up to my application. Some colleges were willing to disclose the information, some not. As has been said, one should be wary of year-on-year fluctuations, especially given the smaller figures involved, compared with the more general Norrington Table.
However, there surely is some discrepancy from college to college: Balliol, for instance, is the most renowned for PPE, and I have heard that St Anne's is rather good for that subject too.
Not "so eager" - just mildly curious.
