Additionally it's now only five games to get an initial rating, although you do have to break your duck.13.1 To be included in the FRL or FIDE Rapid/Blitz Rating Lists, a player must be registered through a national chess federation which is a member of FIDE. The Federation must not be temporarily or permanently excluded from membership.
I rather suspect instability in ratings is going to increase, so with also the lack of stability in ECF grades arising from six-monthly grading, the relationship between grades and ratings for individuals with both ECF grades and International Elo is going to bounce all over the place.
This would be down to new K factor rules
8.56 K is the development coefficient.
K = 40 for a player new to the rating list until he has completed events with at least 30 games
K = 20 as long as a player's rating remains under 2400.
K = 10 once a player's published rating has reached 2400 and remains at that level subsequently, even if the rating drops below 2400.
K = 40 for all players until their 18th birthday, as long as their rating remains under 2400.
