No resolution will be forthcoming, IMHO, as far as I can see.
I view this guide as a first step, but I agree that it is quite vague. someone above both departments needs to realize the conflict and hash out a clear guideline so everyone can get on with their lives. the search guys' paranoia about spammers reverse-engineering their algorithm needs to take a backseat here... there are literally hundreds of signals that they use so, giving clear guidelines for one of the signals is not going to undermine the entire algorithm.
Not revealing the threshhold by which the keyword-density flag is tripped -- ok, I get that.
Not revealing the ad-heaviness threshold is tripped? no, I don't get that considering that the threshold is likely tripped by following the advice of another google department.
