i think the serps are volatile because the results arent created from just one run. it takes a few iterations for it all to settle out. the first time they do it they always get a load of lousy sites float to the top, which everyone notices and complains about, but they never stay there. in my experience if i drop down, i can usually just sit it out and recover.
its when you panic and make wholesale changes, trying to fix non-existant problems, that you do yourself more harm than good.
