The point of the Skill system is to rely on snap judgement rulings, not detailed rules like there were in 3E. It is a feature, not a bug. The designers did not set out to provide detailed cases and final, they designed a fuzzy system on purpose.that is not a good excuse for a poor description though. Just because everything can be fixed / decided by the DM does not excuse the rules from being well thought out
One might prefer a different approach, but it is a disagreement at a philosophical lwvel rather than a particular failure point.
