For those of you that are interested in the topic read on. Others feel free to skip over.
The new rating regulations allows for an initial FIDE rating now after 5 games vs 9 games previously. This makes it considerably less complicated for a player to achieve one. Doing so possibly from a singular event, if properly designed, is feasible.
Previously under the 9-game regulation, you could conceivably achieve a FIDE rating via a 9R-RR event where 4 players would have a FIDE rating and 6 would be unrated. So long as ALL of the unrated players scored at least 1 point (a win or 2 draws against anyone in the field) and their initial rating was above the FIDE rating floor, all of the unrated player would have their initial rating. If they didn’t all score at least 1 point, then the unrated players would only have a 4-game performance norm assuming that performance norm was above the rating floor at that time. This was part of the regulations for RR tournaments.
So this was both good and bad - you could get an initial rating from a single event but there was risk based on the other players. You could conceivably do it in a long weekend with 3 rounds each day. If you kept the FIDE rated players under 2200 then you could use a time control of 60 30. Previously also remember that there could be only 3 games in a single day.
Fast forward to now and there have been a number of changes:
- You can gain an initial rating in 5-games only
- Rating floor has been dropped to 1000
- Number of games per day was removed, only total base playing time can’t be over 12 hours
Now the rating regulations weren’t proofed well because it was intended to remove the ability to score against ANYONE in a field and only have it be for scoring against the rated field. I found this out in communications with the FIDE Qualification Commission.
So where’s this all leading and why am I mentioning this. Right now I have the Exhaustion Invitational going on at my chess center. It was supposed to be a 9R-RR event (3 sections). The schedule would be 1-4-4 Fri-Sat-Sun with a time control of 60 30. All FIDE rated players were below 2200 so the time control was fine. From the schedule you can see why the event was named as such 
Now being told that the score had to come against only the rated players, that made for really some unnecessary games to be played (as those wouldn’t count). However the challenge we have is that there’s no system for pairing a team of rated players vs unrated players under FIDE. Can’t do a RR because we’d have to manipulate pairings to eliminate them. Same with Swiss. There is a system however that would work which would be Scheveningen. Historically FIDE has not allowed the use of this system for initial ratings and it was stopped for title norms many years back (both because of fraud).
However given that now only a 1/2 point is needed out of 5 games, the QC was open to look at allowing this system for initial ratings. So I was able to remove the unnecessary games (unrated vs unrated) and have Team Rated vs Team Unrated and use Scheveningen pairings. This reduces us down to 5 rounds instead of nine which can be done in a variety of ways - normally 3-2 over a weekend but we’re doing 1-4 on Fri-Sat.
We’re now going into the 4th round and in our 3 sections 1 unrated hasn’t scored in our top section and 2 unrateds haven’t scored in the bottom section.
As my average rating of opponents for each section is well above the rating floor, the sole 1/2 point would achieve a FIDE rating (though very low).
For those of you wondering in each section the USCF ratings are pretty much uniform across the board with only a couple of outliers.
What is nice now about this is that the players focus on themselves only as their own results are all that matters, not the results of the other unrated players.
So for those of you interested, this is an interesting (and relatively easy) method of creating more FIDE rated players in your area.
