Interesting, Goathead.
I probably hate the procedure as much as you do; I think it was very poorly designed and implemented. I doubt that it saves any money at all; in fact, I believe that it actually will cost money in the long run from unintended consequences (such as NWS problems, ie, unkown unkowns, etc). I particularly think the designer of this procedure gave it as much though as I did to what I flushed down the toilet this evening.
Having said that, it is now as much a part of the SOPs as anything else. It makes no difference to me whether or not I do it, except when I am in overtime: then I like it a lot!
