Good question, but also why not 1.01 power? Anything higher than one will help fight sybil attacks, and the less 'extreme' it is, the more fair it will be for "normal" users. I agree a more detailed post would be good but honestly my SteemIt related posts have gone nowhere so my incentive to put a ton of effort into something like that is pretty small. This post was kind of a way to see if people had any interest in this topic or not (it's also sometimes difficult for me to figure out what points from the white paper might be known to many and what points aren't) - so far it seems like there is some so, yay!
