RLatSM on NAT Tracks

A bit of help from our ATC colleagues please. I have been reading NATS Ops Bulletin 2015-003 about reduced lateral separation minima in the NAT Tracks and it's implementation in Nov 2015. With the separation being reduced to ½ degree/25nm on designated tracks, I can't see any change to the contingency procedures to reflect that. It seems as if one should still turn 45 degrees left to right and offset 15nm before descending.

I fly a Gulfstream on random routes usually above the NAT (FL430/450) and was wondering if the contingency procedure, should I have to descend through those designated routes, remains the same and also if operators that are cleared for RLatSM have received any updates should they have to descend.

Any help with a reference would be very useful - I have looked at the 'NORTH ATLANTIC OPERATIONS AND AIRSPACE MANUAL' but that still states as above.

Thanks.
