Not quite, they THINK they have figured it out, because their 'results' demonstrate that what they set out to prove based on an assumption, has been proven. It's deductive reasoning at it's worst.
There are thousands of people out there that work night and day, through trial and error, to figure out what is does
THIS is a cat and it is black; Therefore ALL cats must be black.
The prime example of an "expert" (Sumantra Roy) getting it wrong is KEI (Keyword Effectiveness Index). Based solely on the assumption that the numbers Google used to show as the "showing nnn from nnn,nnn results" was accurate. Boy oh boy was he WAY out on that one!
The ONLY thing that does work well, has ALWAYS worked well, works consistently and continues to work is creating a site for your users and Google's users. It may not work "quickly" but it DOES WORK
Algo chasing means starting again when what ever the "experts" thought they found changes, and a website's lifetime of "rank checking" to see if it has been found, SEO is a marathon not a series of sprints.
