There really isn't one.
We have the Encore Guide that that shows examples of the basic reports but it doesn't really explain things in the way that I think you are wanting.

It's the only one I have found and it pertains to the ASV machine but the basics are there.
If you are wanting to evaluate actual numbers that you see there really isn't anything.
You can read the SleepyHead tutorial under construction thread in my signature. While the images are different the basics are the same no matter which way you look at it.
Normally we just post an image of the report and ask for input and clarification of what we are seeing.
It's easier when we can see what you are seeing and having trouble understanding.
Remember Encore was designed for DMEs and doctors who already had a working knowledge of what all the numbers mean.
I may have to RISE but I refuse to SHINE.
