The text you are asking about is two transparent chat windows. Make a new chat window, right click it, and choose to filter your hits to one and your misses to another. Then, in that same right-click menu, choose the number only mode... not full or compact, but i forget what it's named.
I use a similar method, but I put my hits and misses, along with others hitting me in the same small window to the right side. It makes for less to scan during combat.
