<p>[QUOTE=&quot;mrbrklyn, post: 448139, member: 4381&quot;]These tools were brought into play because the human eye was making large mistakes on an industrial scale.&nbsp; Compounding a new drug is not so scientific that it is not subject to human judgments which are faulty and inconsistent, no more so than grading a coin.&nbsp; With experience and knowledge you create mock ups of tableting machinery or raw drug production and then you validate it.&nbsp; And this will probably be done a few times until the mock set up fits within the acceptable guildlines for the agent as defined in the USP.</p><p><br /></p><p>Then they scale it UP to full size, and again have to validate it based on assumptions&nbsp; or misconceptions which may or may not be true.&nbsp; And we work out the scaled up for a realtime version by validating the process and re-validating it until in it is completely predictable within a range of error.</p><p><br /></p><p>And now you can do quality assurance.</p><p><br /></p><p>Now with coins, it is really the same exact thing.&nbsp; You have a grading standard, regardless if it is market based or technical based, it is still a standard.&nbsp; You train people to make grading decisions based on these standards.&nbsp; These graders are NOT supposed to be coin fanatics or experts.&nbsp; They&#039;re just trained workers, who might only know how to properly grade one kind of coin, say a Morgan Obverse.&nbsp; When your done with the entire grading process, with maybe a half dozen graders each working on a specific area of expertise, you then take the coins, and put them through the grading system again.&nbsp; If they come out with different grades, then you adjust the standards to create better precision, and retrain the staff.&nbsp; Ultimately then you have a validated process for grading a coin, in this case Morgans.</p><p><br /></p><p>Ah, now I have a statistical&nbsp; model to gage my quality on.&nbsp; A few coins a week can be used to assure that my grading system maintains its quality and precision.</p><p><br /></p><p>And then you also have hard data to judge the effectiveness of different grading companies.</p><p><br /></p><p>It is really not that hard.&nbsp; It really is doable.&nbsp;&nbsp; </p><p><br /></p><p>However it will not be done and we will continue to argue about 69&#039;s and 70&#039;s or ANACS or NCG...</p><p><br /></p><p>And it is all ego.&nbsp; There is nothing to the grading skill that can&#039;t be taught even to and especially to someone couldn&#039;t care less about the coins, and it would be better if it was that case.&nbsp; </p><p><br /></p><p>Meanwhile the experts create the standards and sit over quality control, and handle the odd coin that is not within the standards.</p><p><br /></p><p>Ruben[/QUOTE]</p><p><br /></p>
