JM7 posted a nugget of information I missed about how DCF is used in this S@H post.

Actually, ROM missed a little. A score less than 1 means that your computer finishes work faster than expected for its benchmarks. A score that is higher indicates that it finishes slower than expected for its benchmarks. It is calculated as a safety for the CPU scheduler (finish on time) and work fetch (not too much), therefore under estimates are corrected very quickly (single step) and over estimates are corrected much more cautiously.

Thanks John.
