Quick question: Is more "Litigation Percentage" good?

[caringdad]

I am a recently divorced dad of my 4 year old in California. I am looking for an attorney to consult to get custody.

I often see in attorney's profiles about their "Litigation Percentage", which is evenly distributed from 0% to 100%.

I want to know:

What does Litigation include?
What exactly is "Litigation Percentage"?
Should I be looking for a higher or lower "Litigation Percentage"?

Thanks
