In any tuning situation, there are two roads to go. Neither should be used to exclusion of the other; both are improved by the presence of the other.
One is to go for the low-hanging fruit, but measure to see if it really helps and and think moderately both before and after. One might assume that the low-hanging fruit has already been grabbed, but if a given approach hasn't been tried and someones willing to do the experiment, let 'em go for it. It often yeilds nice immediate benefits in a short time frame, but rarely addresses the more complex underlying problems. The other is to do full analyis. This is usually good at addressing the underlying problems, but usually involves a lot of theory and a lot gaps between theory and practice. The latter have to be worked out by experiment and verification, which sometimes looks suspiciously like the process used in grabbing the low-hanging fruit. Both methods can and should be used in parallel. Neither should be used to the exclusion of the other. We all have the source. -- Sturgeons Law: "90% of everything is crap."
