If camber specifications are symmetric around zero, what does that imply about the tolerance?

Symmetric tolerance around zero means the allowed camber deviation is the same magnitude in both directions from zero. In practice, the spec is written as plus/minus X degrees, so a camber of +X or −X is within tolerance. That means both positive and negative camber are governed by the same tolerance expression, describing the same allowable range on either side of zero. This is why the correct interpretation is that the two sides share the same form of tolerance. The idea isn’t that camber must be positive or negative exclusively, but that the permissible range applies equally in both directions.
