I expanded the list out to the first 50 sites, that probably accounts for around a third of the Pandalized sites in Google's 500 complaint spreadsheet, since they included everybody who reported rather than only those who were impacted.
I take the opposite conclusion on big sites. Of the 17 sites that were top 10,000 on Alexa (I rounded a little to allow for their pre-recovery loss), 5 recovered fully, around 30%. Only one or two of the 33 lower ranked sites recovered fully, call it 6%, so big sites were five times as likely to recover!
Of course, that doesn't take into account that professional webmasters were more likely to find and report on the Google thread than hobbyists, maybe if I went out to the first 100 sites the ratio would change.
I do suspect that a lot of smaller site owners, like myself, just gave up and didn't do anything for six months. I didn't really start working at it until my hobby site came back on its own in September.
