I did'nt say if you gave a beginner an exagerrated rocker they would not tell the difference, my point was simply the finer details of the rocker are only applicable to the more advanced surfer.
The majority of entry-level surfboards do not have complicated rocker profiles to adapt specific needs and are therefore farily regular. Of course if you were to exaggerate this to the extreme, the difference would be obvious to even a complete beginner.
The foil does have the main influence on paddling ability. The main purpose of the rocker is to characterise surfing manouverability and speed with a flatter rocker producing more speed but less manouverability (suited to a beginner). Since therefore nearly all beginner boards have a relatively flat rocker, the paddling ability will not be significantly affected.
It's pretty irrelevant really because for a beginner the longer, wider and thicker a board is the easier it will be to surf. All I'm saying is the other factors will be fairly constant across the beginner board range and therefore do not need to be analysed to a great detail.
