I concur. When the first dispute from the merger Cmte chair clearly mentions that a column was removed (which actually was column "G") its clear that it was there.

*Column "G" was actually the checkride date, not "seniority/class date". My iPhone app for spreadsheets is making this difficult. Both dates were always there and this issue was discussed from the beginning. Bloch has made it clear he wanted the seniority date (class date) post-dispute so the issue is dead.
