Lets say you measured 0.011 play in the first step. Subtract 0.001 from the play you measured in the first step. The arrows show where you need to remove material. You do need to write down exactly how much play you measure in the above step. In the next picture I will show what to do. If you need instructions on that please post. If you find excessive play, remove the screw. There needs to be about 0.001” of play there but not much more. The picture is a Heavy 10 compound but the procedure is the same for a 9” workshop cross feed.
