1200 criminal cases, 12 additional judges?

This PE articles explains some of the reasons for the backlog of 1200 criminal cases. http://www.pe.com/localnews/inland/stories/PE_News_Local_D_longtime10.27e2ab3.html
While I hate to be a killjoy, 12 judges for a backlog of 1200 cases sounds inadequate. If the current group of judges can maintain the status quo, then the 12 judges will each have a 100 cases to resolve. If each case lasts two weeks on average, and if the average judge takes off 15 holidays and four weeks vacation, that means that each judge will resolve 22 cases. 12 times 22 is 264 cases. Hmmm. That means in about five years will resolves this gridlock. Given the counties increasing population growth, and DA Pacheco's refusal to budge, it doesn't look good.
