Just to make sure I understand - are you saying that on a properly loaded ship, no more than ten seconds should pass between the deck going out of level and then returning to level? Does it matter if it's rolling side to side, or front to back?

There's a certain design range where it's not too fast and not too slow, and some inspectors check for it. https://en.wikipedia.org/wiki/Metacentric_height#GM_and_rolling_period https://en.wikipedia.org/wiki/Metacentric_height#GM_and_roll... Also, there's random motion that may look like roll when it's the sea surface that's showing the motion, so there are methods to filter that out and extract the actual rolling period.
