Thinking about NFP impact vs. market reaction - what's the typical lag for full repricing?

Still trying to get my head around how the market fully digests major data like NFP. I see the initial spike/drop in pairs like $EURUSD or equities, but then there's often a retracement or further move over the next few hours. Are traders generally looking at a few hours, or is it more like end-of-day before the 'true' repricing of the news is mostly done and stable?
