I think most of the obvious plot holes are due to a combination of Rowling being bad with numbers and the PoV character having literally been raised in a closet, thereby making him an unreliable narrator. A lot of other supposed plot holes can easily be resolved using actual canon.
I'm reminded of another internet argument where the other poster basically claimed Dumbledore was a moron for not guzzling Liquid Luck at every opportunity and crushing the Death Eaters. I pointed out the multiple ways that canon proved his master 'plan' wouldn't work, but he was so fixated on his own headcanon that he refused to believe actual, verifiable facts.
In case anyone is interested in my take on the Liquid Luck argument:
Fact: Liquid Luck is highly toxic when you take too much.
Fact: Slughorn is so good at making it that he can give some away as a prize in his potions class.
Fact: Slughorn said he used it twice; at ages 24 and 47. He may have used it a third time at the Battle of Hogwarts.
Conclusion: If an expert like Slughorn waits over twenty years between doses, taking Liquid Luck more than once every several decades is probably a very bad idea.
Fact: Ron Weasley took some and managed to survive fighting Death Eaters.
Fact: Ginny Weasley took some and managed to survive fighting Death Eaters.
Fact: Hermione Granger took some and managed to survive fighting Death Eaters.
Fact: Albus Dumbledore claims to have taken it recreationally.
Conclusion: Liquid Luck does not turn you into an unstoppable combat machine.
