If I set the pink track to any output(or none) Delay Comp does nothing(as expected). I can add a send to the bus for side-chaining to the duckers. BUT, if I try to set the pink track's OUTPUT to the bus, ADC adds compensation of 1177 samples, for no apparent reason. Anybody got an idea why?

dummy = output to nowhere

Chief Technician is right. Even if your bus is going to a sidechain key input of a compressor, your bus, albee1952, is going to nowhere else (and the ADC algorithm is a bit lost). If you want to output your audio track to a sidechain key input, 2 options :
1/ you must create a "dummy" muted Aux track (sidechain bus = input, "mix" output = output) then ADC algo could calculate the proper delay (here = 0).
2/ or use Sends like you did.

AFAIK, busses simply have to be terminated*. Especially, if there is complex/unusual routing using busses leading to another bus or to "nowhere" or to plugins.
* = make sure all your busses are routed to an aux track (even if you don't need one, then use an dummy aux track like described above). Note that busses routed to audio track are not terminated except if input monitoring is ON (HD only) or if RECord is armed.
