Great information, Steve. It seems there is a world of difference between what a TPG can detect with minimal equipment on a one minute review and what COULD be detected with sufficient time, money and training. And I would even question whether TPGs could detect a lot more than they do if they really cared to, even under present review conditions. Unless Steve corrects me, I stand by my thesis that when solvents are used to remove stains from cards, there will be detectable changes in the paper.
