I don't think there is an exact answer here. Most of the issues you are talking about have more to do with the storage, age, time, and manufacturing of the lumber. So basically you will have a couple of people working at HD or Lowe's that contract out to mills or other lumber yards to get their pallets. Of course "older" lumber is cheaper. But you don't ...
In the big picture, if you order a lumber package from a reputable lumber yard, they'll replace any boards that are not usable. So technically, "Zero." Practically, it may be cheap "insurance" to order one or two extra of what you deem to be the pieces that would most halt your forward progress at a critical phase of the operation.
