Isn't it maybe the case that EU citizens such as Karger, Bukhave -- and now Romano Hummell -- are indeed assessed and their CMA can't drop, but once they have done 4/4 they could be released if form doesn't warrant keeping them in a team on their 5, or 7?
Jye Etheridge is perhaps a different case, as he's a 'foreigner' on a visa, and must be guaranteed employment?
