If there is a stretch of laydowns I would prefer to move across them and cycle my way back around again. If it happens to be one specific laydown and you catch 2 or 3 on it I would probably stay there no more than 20 minutes before moving on.
Remember that spot and come back later. Sometimes it may just need time to "rest", "refresh", "recycle" or whatever else you hear people refer to when it comes to wearing out a spot.
