Recently I was improving one section of website to make it better, I expected improvement in ranking for those areas but to my surprise I got improvement in another area where fresh content or improvement was not done since long.
It prompted me ( some other incidents also ) to think google has one confuse module which takes care of its secretes and it never allows any webmaster to conclude anything or to arrive in any cause and affect conclusion. Probably after every evaluation process or ranking changes they may be executing this confuse module to protect their ranking factors from exposing.
So I decided not to focus in one area for long time and keep rotating or working on different areas of the same website so some time or other one improvement will be brining result.
