Today's bots act like browsers (chrome included) and often send spoofed headers. This in my opinion renders raw logs files useless (except for providing quantified daily "hits").
I'd guess that many people who use log files assume that various things may be spoofed. It's why a person might look at user interaction and how that interaction transpires.
Your "hits" comment I find interesting. Do you really want to stand behind the opinion that people looking at server logs are just counting hits?
All of it is really moot at this point, there is no serious analysis to be done because the general public has other concerns and are following seasonal patterns. Second or third week in January other patterns could be discussed, doing it now is just watching your words on a screen, analysis doesn't make sense unless your business is Holiday specific.
