And again, if one wants to exploit something for the purposes of showing it in a best case scenario, then it is quite easy to do. Does that reflect reality? No, it never has and it never will.
Have you actually done any tests to see if reality comes close to these reports? I know you have not, as I have and they don't. It is hit and miss, at best. Of course, I am not going to run things for the purpose of showing a best case light. I prefer three cases. Best, worst, and average. It tends to be more reflective of reality.
Now, show me a site who has done that, and then you will have something to talk about.
How many times do you have to be shown that best case scenarios never reflect the real world? They are for wowing the ignorant so they will propagate that "fluffy" information. Marketing at its best.
There are already real world reports, floating to the surface, showing the lack of any performance gains in many situations.
