My estimate of one year for completion was completely naive and inadequate; I didn't factor in life's interferences.
As of Nov 2016, I am down to the last 16 states, the "busiest" ones, comprising 71% of the sheets.
As of Sep 2016, I have completed 24% of the groups sheets in 32 of 52 subdivisions and removed another 50 sheets.
In addition we have had a busy few months and have added 85 new sheets.
As of June 2016, I have completed 19% of the group sheets and 30 of 52 subdivisions for the site.
In addition, I have removed 210 duplicates.
