As of yesterday, I found 131924 unique certificates (either in final or 
precertificate form) in CT logs where the issuer contained the string "wosign". 
 Of these, 62412 have notBefore with the year 2015.
Of the total set, 20723 have already expired (15.7%).  Of the 2015 certs, 9380 
are already expired (15.0%).

Based on the 230K total number, it seems save to assume about 196K certs are 
probably unexpired at this point.  Does that seem accurate?
