I can only assume that what he mentioned in 4.2 of the NAPS scheme more than accounts for it - bear in mind that WW is independent of BA pensions, and WW LLP's selection is up to them.
I would have assumed that whatever enhancements are made behind paragraph 4.2 would have made '80 figures more appropriate to the demographic profile of NAPS members perhaps? I can't help any more than that however, since I am not an actuary but a chartered accountant.
