so the values you see is the percentage fuel increase at that RPM at the throttle position. so if you see a 10 in a box it means 10% over stock fuel will be added at that range. if it is -10 then we are removing fuel at that specified range. Ideal is to get a nice A/F mixture like 14.2 . run bike idle lean sop negative values low, mid range run it rich, and towards top end lean it back out again
