Scientists studying how current really moves through wires and other objects.

Are you implying that those here are not qualified to make a judgement?
If so, then this forum is just a waste of time.

Now if they'd only use this to compare OCC and OFC copper...

Apparently, they may have....

In contrast, the electrons in a normal conductor, like the wires in computers and walls, don't interact much. They are much more influenced by the environment within the conducting material—often impurities in the material in particular. On the individual scale, their motion is more like that of perfume wafting through the air than water rushing down a pipe. Each electron mostly does its own thing, bouncing from one impurity to the next like a perfume molecule bouncing between air molecules. So electrical currents tend to spread out and flow evenly, all the way up to the edges of the conductor.

That statement implies that they've already researched common wires  already being used. It would be nice if research of that type were more fully available.
