<p>[QUOTE=&quot;brokrken, post: 5242233, member: 111910&quot;][USER=15309]@Lehigh96[/USER] I don&#039;t know that this statement is true.&nbsp; The logic you used would say that the average variance would be 0 if, for instance, there were 6 coins and on 3 we were 2 grades high and on 3 we were 2 grades low.&nbsp; When, in reality, we were 2 grades off on every coin.&nbsp; If we use this logic and look at the absolute variance to grade (rather than the +/-) the data shows that on average we are 0.624 off on ICG and 0.6025 on NGC.&nbsp; So, I would argue that we grade about the same relative to both TPGs[/QUOTE]</p><p><br /></p>
