Double Up

TODAY was the first of two double-round days in the Malta Open.
This morning I positionally crushed a 1659.
In the  evening I drew a pawn-down against a 1763 - someone who before the game began recalled beating me 15 years ago in the Linares Open (I also knew I'd lost that game).
This puts me on +1=2-1 for a loss of 9.8 Fide elo.
I am actually playing quite a bit worse than those figures would suggest - my loss came to a player who does not have a Fide elo, so my Fide rating is not penalised for losing to him.
After four rounds my tournament rating-performance, if translating the unrated's ECF grade into a rating, is 1657 - 283pts below my Fide rating of 1940.
