Apologies - to the BEA AND for the double post:
The relevant BEA appendix in the latest report does give the power settings. 'Rough copy' says:-
2.10.47 33%
2.10.56 TOGA
2.11.43 MCT
2.11.56 TOGA
2.11.51 TOGA
2,12.07 CLB
2.12.33 TOGA
2,13.48 CLB
2.14.09 IDLE
2.14.18 TOGA
They do indeed appear to have used the detents all the way down - with just the one exception at the beginning.
