Mp tune calculated tables,rpm vs psi

I noticed that on my OTC 4000e it shows my timing at idle is ten degrees. I also see that at WOT it shows zero degrees. I also see on my smec tune full throttle calculated table that most of the numbers are 10's but as you increase rpm and boost the numbers get larger.
Question, what timing do the tens represent. What do the numbers larger than 10 represent, are they added to the number ten to show total timing? Do they mean anything at all? Does anyone on this blog have any idea how or what these numbers represent. How can I ever determine what my actual total timing is so that I can determine if it needs to go up or down. The 3D chart is useless because you can't even read the boost number line to try to make head or tail of this because it's so cramped together.
