What does Rtg, RtgF and RtgN mean (in the context of a chess tournament)?

I've noticed that when they publish a list of players entering a FIDE rated tournament in Australia, it lists the following things:

- ID

- Name

- Fed

- Title

- Rtg

- RtgF

- RtgN

I've also noticed that for most people, their Rtg and their RtgF are the same, with only a few exceptions. But most people have a different number for their RtgN.

What does all of this mean?

Okay so I think that:

RtgF = FIDE rating

RtgN = National rating (ie. ACF rating for those in Australia)

Rtg = ???

I don't think it means "rating difference", since the tournament hasn't started yet.

RtgF=FIDE rating

RtgN=national rating

im not sure about rtg, maybe it means rating used for the tournament? i think that sometimes if they dont have a fide rating they will use their acf rating

maybe show an example and i can figure it out.

Could the 'Rtg' be rating performance for the tournament?

In australia, usually it is displayed as PRtg

Nah I don't want to embarrass myself in front of the tournament director. I'd rather just ask anonymous people off the internet.

I think this is it. So for a tournament that is both FIDE and ACF rated, I think they go by FIDE ratings, hence why rtg and rtgF are usually the same.

Does anyone know what PRtg means?

Probably Performance Rating

thanks
