I explained this the other day:
Imagine two people are being sentenced for a crime that they did in fact commit.
The first guy goes before the judge, and the judge looks down and sees not only has he not shaved, but his shirt is untucked, his hair is a mess, he's only wearing one shoe, and he's eating a chocolate bar, while listening to his airpods, and high-fiving his friends and winking at the female court bailiff. The judge asks him, " is there anything that you would like to share before I pass sentence?" He doesn't even hear her because he's too busy nodding his head to the latest jam. So she passes sentence.
The second guy goes before the judge, and he's dressed in a fine black suit, fully shaved, hair fully coiffed, and he enters the courtroom with respect, head slightly bowed, and when the judge asks him, " is there anything that you would like to share before I pass sentence?" he quietly launches into a well prepared and compelling monologue about admitting guilt, turning over a new leaf, and begs the court for mercy. He gets half the sentence of the first guy.
People who are more careful during A"YT are embodying the second guy. Its not a trick or a ruse, assuming one is genuine. It's simply a recognition that these days differ in kind to the days before and after it, and striving to bite off a bit more in pursuit of ratzon Hashem can only help.
ETA: bah, I see it was mentioned while I was typing.
