For what its worth I was in the hold pool but don't have the TR for this round. I applied to BA twice and got to the first assessment both times. The first time there were 7 days froms application to invite, the second time it was 6 days.
From the letter I got from BA, the recruitment now is to have people ready to start in the next financial year i.e. after 1 Apr 11. This is the reason for the TR requirements so they can train you quick starting in Apr and have you on line for the summer.
