So with a 2pole 12 way rotary, it could look like these.

Step 1, Attenuation = Infinity dB, Rx = 50000 ohms, Ry = 0 ohms, Resistor = 0 ohms.

Step 2, Attenuation = 35 dB, Rx = 49111 ohms, Ry = 889 ohms, Resistor = 889 ohms.

Step 3, Attenuation = 28 dB, Rx = 48009 ohms, Ry = 1991 ohms, Resistor = 1102 ohms.

Step 4, Attenuation = 24 dB, Rx = 46845 ohms, Ry = 3155 ohms, Resistor = 1164 ohms.

Step 5, Attenuation = 21 dB, Rx = 45544 ohms, Ry = 4456 ohms, Resistor = 1301 ohms.

Step 6, Attenuation = 18 dB, Rx = 43705 ohms, Ry = 6295 ohms, Resistor = 1839 ohms.

Step 7, Attenuation = 15 dB, Rx = 41109 ohms, Ry = 8891 ohms, Resistor = 2596 ohms.

Step 8, Attenuation = 12 dB, Rx = 37441 ohms, Ry = 12559 ohms, Resistor = 3668 ohms.

Step 9, Attenuation = 9 dB, Rx = 32259 ohms, Ry = 17741 ohms, Resistor = 5182 ohms.

Step 10, Attenuation = 6 dB, Rx = 24941 ohms, Ry = 25059 ohms, Resistor = 7318 ohms.

Step 11, Attenuation = 3 dB, Rx = 14603 ohms, Ry = 35397 ohms, Resistor = 10338 ohms.

Step 12, Attenuation = 0 dB, Rx = 0 ohms, Ry = 50000 ohms, Resistor = 14603 ohms.
