I would like to add the -350 penalty. One page was number 5 in SERPs for over 2 years, now #355.

Many search phrases not affected - still in top 10 results.
Many search phrases ARE affected - gone from the top 10 to somewhere past 100.

This is very puzzling - very few changes to the 9 year old site. But the SERPs have been hit with the "mixmaster". I can't find any common thread. At first, I thought it was a penalty. But now I am leaning toward "another algo improvement" with unanticipated poor results. Throwing out the baby with the bathwater, or something of the sort. Hopefully, more testing will give us some hints.
