Traffic gains are absolutely incremental as well, not just recoveries. If you don't have something that 'goes viral' or you didn't just add a huge amount of new content then your traffic will not move by leaps and bounds. Google has a patent on adding a time delay to serps changes where if a site is suddenly the best for a result but it was previously number ten it may take six months or more to rise to number one. By that time it may no longer be considered number one and may never reach the spot it deserved for a time. The inverse is also true.
