The Laser Radial sailor opened her Spanish adventure with two victories on the opening day and followed that up with the same results on Tuesday.
Young remains atop the standings after day two, and having finished fifth at London 2012, the 25-year-old admits that she is already working towards how to improve at the Rio Olympics in three years time.
"It's been a great start to the regatta so far," she said. "Another two bullets so I can't really ask for much more from the start, but the real racing begins on Thursday.
"It is quite nice having 'nil points' though, I might try and keep that going a little bit longer. We’ve got a bit of a mixed fleet.
"A lot of the girls from our fleet have jumped into the new classes which have come in, so it'll be quite an interesting season seeing who’s staying, who the new faces are and what the fleet’s like.
"After the Games when you come fifth and you see the rest of the British guys picking up their medals, you think 'I want to make sure that’s me next time'. You see all the little areas you can make the gains in, and that's motivated me to get back on it.
"Definitely, this is the start of the campaign for 2016."
Sophie Weguelin and Eilidh McIntyre were also boasting a perfect record after day one and, although they had to settle for two second-place finishes on Tuesday, the pair held on to their lead at the summit of the women’s 470 class.
Two second-place finishes were also what RS:X women's windsurfer Bryony Shaw walked away with on day two to move her up to third overall.
Olympic Yngling champion from Beijing 2008 Pippa Wilson returned to the water for the first time since 2009 alongside John Gimson in the 17 Nacra class on Tuesday, recording finishes of second, 13th and ninth for seventh overall with compatriots Ben Saxton and Hannah Diamond three places ahead in fourth.
"It was really good fun and exactly what it's all about, properly challenging in every way," 27-year-old Wilson said. "It was very fast, with some quick decisions learning to race at that speed.
"There are some big mountains to climb but a great first day. I really, really enjoyed it. It's going to take a while to learn this fleet and how the distances open up and make a bit of a plan.
"It's been great to come here and line up with the foreigners and get a bit of a feel for how our speed is. We felt our speed was pretty good actually, once we could get out our heads out of the boat and race a bit better.
"So that's great, and just to see what everyone else is up to so we can move forward from there."
Elsewhere, in the new 49erFX women's skiff Charlotte Dobson and Sophie Ainsworth were the most consistent of the British crews and are placed seventh overall, while in the men’s 49er fleet Stevie Morrison and Ben Rhodes ended their first day on a high with a race win in the fourth of their races, atoning for a capsize in the first.
The two-time Olympians are third overall, with Dave Evans and Ed Powys level on points with their teammates in fourth, and with development squad duo James Peters and Ed Fitzgerald putting in an impressive display to sit in sixth overall.
Giles Scott remains in second overall in the Finn fleet after four races, although teammate Andrew Mills saw the best scores on day two with two third places seeing him in fourth overall.
Mark Andrews boasted a race win to end his day and now sits in seventh place in the Finn.
Luke Patience and Joe Glanfield maintain their steady start in their first event together, poised in fifth after four races, while Tom Squires and Nick Thompson are the top-placed British sailors in the RS:X men's and Laser in 14th and 18th respectively.
