Obiwan's guidance had a calming effect and allowed Luke to clear his mind and take the shot. Without Obiwan, he might not have made it.
Then again, he might have, considering he was already a skilled pilot who, by his own words, routinely made similar enough shots back on Tatooine in his T16.
I didn't say Obiwan took the shot for him. That obviously never happened. What did happen was that Obiwan guided him before he took the shot.
I combined these quotes because they were connected.
Dude, he was a farm boy in some hick planet taking shots at some alien road kill whom we don't even see so they could be easy targets for all we know. If all he needed to make that shot was self imposed training on road kill with his shit calmed then either the shot wasn't that hard to take, or it's awfully convenient how Luke is able to use the force (Obiwan's 'calming' effect or no) to this significant of a buff on his aiming skills after a single exercise in it.
Yoda said that in Return of the Jedi - which takes place 4 years after Empire. That changes everything.
The training Yoda gave him was complete, but that didn't mean there was nothing else to learn.
So, what, Luke comes back after 4 years of doing god knows what and Yoda just says his training is complete? That was the last part of his experience, level grinding on offscreen characters?
I think you're taking some liberties with the narrative that you're not with the narrative of TFA. Your complaining about how Rey was able to fight off Ren, and how he has so much more training than her. All you know is very broad generalities. You don't know how or why force mind reading works. Nor do you know what kind of training Ren had. But Luke doing whatever off screen is enough justification for his training as a Jedi Knight to be complete?
Luke was proficient by the end of trilogy. He was not in ANH. He was making progress in Empire. He had it Jedi.
You can make the same argument about Rey, really. We know she is proficient in the force, whose existance was confirmed by Han and demonstrated by Ren, and guided by that tiny orange female yoda lady. This is clearly a new skill for her, but she is one of those shonen "I have no skill to use this spirit energy power, but I have a shitton of it that I can overwhelm my opponents with" tropes. I mean, even Luke hadn't gotten flashbacks when he touched his goddamn fathers lightsaber. The movie made special emphasis on how she's basically crazy strong with the force, so it is, by definition, clearly established. If you can point to me what you consider a skillful demonstration of force in the movie, I'd like to see it, because all she does is a couple basic tricks she's seen others do. Rey's proficiency is minimal here. She just has a ton of it to use, against a guy whose apprently shit in it.
