I decided to post this to help a few folks that seem they still are having trouble figuring these out.
First Photo: 1970-S RPM001. Notice the RPM with Blue arrows are full/raised just like the primary punch. This is what you should be looking for as an RPM. Serifs, Curves that are raised in comparison to the field:

Second Photo: this is the same RPM001 when the dies have worked just a bit loose, when the coin/planchet was struck. Notice it looks like there is just a raised line that is the tip of the shelf, then notice the flat/shelf like surface underneith? AKA Shelf doubling / machine doubling / ejection doubling / worthless doubling - all the same.
The raised blue arrows show the RPM, The YELLOW arrows on the top of the date and above the mintmark/ along with the RPM are all visible in the photo.

I will say, in my past, the attributers would rather photograph a coin with a tight die. No MD. A problem coin with MD makes it tough for folks to see the actual RPM or Double Die and sometimes cannot be photographed.
I hope this helps the folks still having issues.
