Donald,
I'm currently working on the Scott Snyder Detective run and should have all issues from 871-881 updated today. For the Golden age stuff several adjustments were made for grades that sold recently from Detective 80 to 84. You won't see these appear on the recently changed list because all values didn't change. There were quite a few middle grades that saw jumps. Those old Tec's are so amazing to me and extremely difficult to find.
