Aug 5th saw an algo tweak and a sudden drop of traffic for many. Aug 23-25 saw another algo tweak where sites that suffered on Aug 5th regained traffic but other sites lost 70%. Sept 22-23 seems to me similar to Aug 5th algo tweak where sites that suffered on Aug 23 regained but sites that got hammered on aug 5 were hammered again.

Yeah, I got hammered starting on Aug 25th, with a 60% to 70% drop in traffic. A few of my pages held their positions, but most got buried in Google. Traffic (and Google positions) came back on Aug 23rd (actually started part way through Aug 22nd), when Google did a deep crawl of my site, even better than before, and has remained steadily strong since then.
