Please name the scenes. Because Biggs calls Luke "the best bush pilot in the Outer Rim Territories", but that's a Special Edition add-in scene that doesn't happen until right before the Death Star assault, and "bush pilot" is exactly why I compared Luke's piloting "experience" to a Grumman Ag Cat.
And? Being a brush pilot qualifies you to fly an X-Wing. This is established in-movie, not only does Biggs think that's the case (and he's a brush pilot himself), but Red Leader agrees when he says Luke will do after hearing Luke's a brush pilot, and Luke proves it because he's a good pilot in an X-wing.
Of course if you have a scene where somebody says otherwise, you'd have an argument. Otherwise well, that's how the universe works and the only reason there's any argument is your insistence that it doesn't work that way when it manifestly
does. You might as well complain that Han should need decades of special college training to work on the Falcon because spaceships require a rocket scientist to work on, or complain that there's no such thing as FTL travel so Luke should have died of old age on the way to Alderaan.
For Scenes? Kenobi references it in comparison with Anakin. Luke mentions it in the bar. Biggs mentions it to Red Leader and the (probably) most veteran pilot in the Rebellion agrees.
Again, Luke demonstrated superior offensive and defensive skills to every other Rebel pilot in the Death Star attack. At worst, he's tied with Wedge and Biggs, both of whom are highly experienced veteran aces.
Since you're playing the "demand exact scenes" game I'm going to return the favor. Show me the scene that establishes that Wedge and Biggs are highly experienced veteran aces and not brush pilots themselves.
Come to think of it, since you pulled out the novelization in your message, I'll go ahead and point out that Luke talks to Biggs on Tatooine while the droids are landing in the escape pod (He saw the Star Destroyer with his electrobinoculars and was talking to Biggs along with Camie and Fixer about it), which establishes that Biggs is
also a brush pilot who has only a few more days in the Rebellion, a week at the
outside given how long it takes Luke to get to Yavin from when the droids land. Your complaint is a brush pilot is as good as... another brush pilot?
"The inexperienced newbie is 'only' tied with the best-of-the-best aces" is classic hero's arc plotskills.
And Han Solo is, at this point, established as the best-of-the-best ace?
Luke who has never even seen a gun turret like that (unless you count the ANH novelization mentioning he's used such guns hundreds of times in his imagination) achieves shooting on par with Han who has literally years of experience with that exact mount.
How many years of experience? How do you know Han's been using that mount as much as you claim? I can't help but notice the
Falcon needs four people to use those mounts (Pilot, Copilot, and 2 gunners) and he's got exactly two people, himself and Chewbacca, normally available, and as we see in every other scene, Han normally does the flying with Chewbacca as copilot. How often did Han get to use these guns?
A lot of your arguments seem to boil down to claiming other character must be better than they're established as being and then claiming that Luke's a Sue for managing to tie with somebody who has... not much more experience than he has. And you miss the point entirely doing so.
They're markers showing that Luke is a brash, naive, and inexperienced kid who has a good heart but very little comprehension of his own lack of skills and experience. Which is a consistent characterization of early-era Luke, and consistent with the hero arc.
They're failures, the very thing that Rey
lacks and that people point to as making her a Sue. I don't personally entirely agree with that but I understand where they're coming from. Rey isn't permitted to fail and it hurts the story in numerous areas.
The difference is that the rest of the movie clearly establishes that Rocky has prior training and experience as a boxer. Luke in ANH is the classic "Heero Protagonist" whose plot-driven skills come out of nowhere. Which, again, is consistent with the epic hero story arc, but what I'm saying I object to is holding Rey to a totally different standard when her demonstrated skills are far less extreme than Luke's.
And the prequels establish that Rey has lots of prior training and experience in her wide assortment of super skills... where?
That said, you're limiting things to one narrow subsection again, and completely missing the point. Establishing skills is good storytelling but it can be handwaved, such as Luke's "best brush pilot" line, that's all it really takes. The point at hand is
failure.
Rey's skills are far more extreme than Luke's. Rey has a massive list of accomplishments from taking down multiple opponents with a staff, to beating Finn effortlessly, to repairing the Falcon when Han couldn't, to learning Mind Trick from seeing it once, to defeating Kylo Ren the first time she fought with a lightsaber (after Finn was beaten effortlessly), to lifting hundreds of boulders with only a few days of training where Luke was managing one rock. But all that's forgivable, plenty of heroes, and heroines, have obscenely good skills because that's heroic. Leia never misses a shot in the OT, for instance, and nobody wonders how she can use a blaster or complains that she's a Sue. Rey can do stuff, sure.
What Rey can't do, is
lose. And that's the point you've managed to miss in my previous post, the anti-sue marker isn't explaining where skills came from, it's the hero getting a bloody nose and getting back up again. Sues don't ever fail. If Rey had lost to Kylo on Starkiller Base and was only saved when Chewbacca strafed his position in the
Falcon, that would be a strong anti-sue marker because she
failed. If she didn't manage to effortlessly beat down multiple larger, better trained opponents on Jakku, that would be an anti-sue marker because she
lost.
Luke needs saving in the movies. Han needs saving. Leia needs saving. The entire Rebellion needs saving.
Poe needs saving. Finn needs saving. The entire Resistance needs saving.
Rey never needs saving, she does the saving herself.
Basically what Rey is missing, is this:
