We have a script in CCCL that will compute a more convenient hit rate number that you are welcome to steal: https://github.com/NVIDIA/cccl/blob/main/ci/sccache_stats.sh

Example in our CI log: https://github.com/NVIDIA/cccl/actions/runs/11574973643/job/32222977763?pr=2646#step:5:1434

Thanks very much @jrhemstad ! For the moment, we're looking to add the stats in their rawest form to logs, to be scraped by some automation that folks in RAPIDS are working on to help with profiling CI.
