This system offers NONE of the meanings of these words that seem to be so prevalent in this forum. I am with many others on the basis of replacing the current system with another but for now the current system at least employs two of those four apparently popular words defined above. Unfortunately it seems that all four are needed to make everyone happy because they are all dependent on each other to be fully realized. And that is a difficult threshold.
