Google Reveals Spam Scores Accidently?
Spotted over at PeterD, A DigitalPoint Forums thread that reveals some interesting data. Basically, a member clicked on a cache link of a page and was presented with the following from Google.
pacemaker-alarm-delay-in-ms-overall-sum 2341989
pacemaker-alarm-delay-in-ms-total-count 7776761
cpu-utilization 1.28
cpu-speed 2800000000
timedout-queries_total 14227
num-docinfo_total 10680907
avg-latency-ms_total 3545152552
num-docinfo_total 10680907
num-docinfo-disk_total 2200918

Look at some of those values; "e_supplemental," "pagerank_cutoff_decrease_per_round," "supplemental_tier_section," "use_experimental_spamscore," "use_spamscore" and "using_borg."
Very interesting but no confirmation from Google, of course.

Those look like configuration parameters, possibly used by whatever software is communicating with the query processor.
I doubt there is any information in there that is relevant to reverse engineering the spam scoring process. The page in question looks like it's a forum post (in Arabic, so I did not click on the link to look at it).
