Power Cord Length

Here's one for the electric wizards to kick around. Whilst attending Axpona this weekend I was doing some power cord shopping. At one particular display I was being told by a very well known cable company representative, I'll not mention the name so it doesn't influence any responses, that the rule of thumb is that in order for the pwr cord to be effective it needs to be at least five feet long. This allows the current to be in the cord long enough for it to be effective. Ok, I'm really dumb when it comes to this sort of thing so maybe I said that in the most simpliest of words but that's pretty much how it was explained. Anyone care to elaborate on this good or bad?

Without getting into the debate of long or short cables and what sounds better or if aftermarket cables makes any difference...based on my experience with at least half a dozen high end cable manufacturers, they recommend to stick with standard lengths simply due to the best value, in-stock availability and future resale.  

From what I have seen, the most common std. lengths being sold are 5' power cord and 6' or 2M speaker cables. 

I have owned from 3', 5' , 6' and 10' power cords with absolute no audible degradation in any of those lengths.
