Now that may be just what Draco needs to realize that something’s wrong with Harry’s story. Maybe Harry didn’t know the timing well enough to fall at the correct second and had to listen for the crack.
What do you mean? He narrated the whole sequence before the explosion, and fell to his knees at the moment Voldemort supposedly died, which is coincident with the explosion. I don’t see a problem, let alone one that would be fixed by shifting the narrative back 20 seconds.
Due to the finite speed of sound, the explosion would have had to occur approximately 20 seconds before they heard it. So if Voldemort’s death was coincident with the explosion it would had to have happened about 20 seconds before Harry said it did.
She’d just about decided that this had to all be a prank in unbelievably poor taste, when a distant but sharp CRACK filled the air. [...] “It worked,” Harry Potter gasped aloud, “she got him, he’s gone.” [...] “I think it’s in that direction.” Harry Potter pointed in the rough direction the CRACK had come from, “I’m not sure how far. The sound from there took twenty seconds to get here, so maybe two minutes on a broomstick—”
Shouldn’t Harry have fallen to his knees twenty seconds earlier, if he originally heard/saw the explosion via Voldie-simulcast?

He was claiming to be dipping into Voldemort’s working memory, not experiencing it directly—that’s why he knew what happened to Dumbledore.
Anyway, that could plausibly provide a level of insulation.
We do not know at what speed does information travel through the Riddle link.
Harry implicitly took it to be instantaneous when he mentioned the 20 second delay.
