I was thinking that pruning was limited in extent — to the region so far affected by the deviant. Which ought to spread at the speed of light, although I can see the comic book effect only counting large effects and being slower.
It Seems the amount of time which is pruned before there is a more severe event is small .. just a few minutes. I don’t see how that could reach back to Sylvie’s conception.

I think her timeline purge was more serious because various spoiler articles are saying she was re-enacting the battle between the Valkyrie and Hela, as if the Valkyrie won, instead of being destroyed by Hela. And that would be a major deviation from the "Sacred Timeline" and for some reason it took them many years to get there and prune that entire branch. I am betting them taking young Sylvie was just collateral damage and she was meant to become one of their mind-wiped TVA employees after she grew up. This makes me wonder if they actually let variant timelines grow and mature, until there is someone there that they think fits into the TVA. That is when they swoop in and kidnap that person and then wipe their timeline/universe out, making them an orphan in more than one way.
