Welcome Nabz
I will add my welcome to you Nabz, welcome to Flyertalk, and to the BA board in particular - and I hope we see plenty more from you in the weeks ahead. Welcome on board.
In a sense, for the lifetime targets for Gold and GGL, there is an element of rolling years, and the two week flexibility has been mentioned. But I know that BA's senior management are very pleased at how BAEC works for the airline, so I don't think they will see any business case for changing it in a significant way.
