Timing Tab Question?

Here is my timing tab. I just installed a new HEI and borrowed an inductive timing light from a friend. How do I read this tab? I see where the 0 mark is but what does the A and the R stand for?

From what I read on here I want to get 8-12 degrees on idle.

Is that towards the R or towards the A?

Im new to all this so thanks in advance for any suggestions or help.
