How long after your babies teeth cut through did it take for them to be fully out?

My babies bottom teeth are coming out. For a few days there was consistent progress but for a couple of days now they've stopped in their tracks. One tooth has fully cut through the gum but the other is yet to follow. I've read it takes about 8 days usually. I'm assuming once they've cut through they'll keep erupting until fully out but just wondering about other parents and their babies timelines.
