Notes: The horizontal bar (-10 to 30) represents the player's level.
The yellow bar represents the success bandwidth.
The examples assume the PC's ability score is 14.
Example #1: RL=1, RDC=1 positions the band farthest to the left
-10 -9 -8 -7 -6 -5 -4 -3 -2 -1 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30
                   
Example #2: RL=20, RDC=20 positions the band farthest to the right
-10 -9 -8 -7 -6 -5 -4 -3 -2 -1 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30
                   
Example #3: RL=6, RDC=11 centers the bad at level 6 (RL=2, RDC=20 and RL=10,RDC=1 have EXACTLY THE SAME effect)
-10 -9 -8 -7 -6 -5 -4 -3 -2 -1 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30
                    RL=6, RDC=11
                    RL=2, RDC=20
                    RL=10, RDC=1
