No differences in collider geometry or Unity configuration.
Possible test cases for determining the cause of discrepancy
Test payload: Mk1-2 Pod + SDHI Heatshield
Side-by-side unaltered comparison (SM/AR sitting on pad)
Side-by-side unaltered comparison (SM/AR suspended by launch clamp)
Side-by-side unaltered comparison (SM sitting on pad, AR sitting on Rockomax Brand Adapter 02)
Side-by-side unaltered comparison (SM sitting on pad, AR sitting on Rockomax X200-16 Fuel Tank)
Side-by-side unaltered comparison (SM sitting on pad, AR sitting on Rockomax Jumbo-64 Fuel Tank)
Increasing the mass of the AR from 0.48 to 1.1 had no effect on decoupling distance.
Replacing the AR model and stack node definitions with the SM model while keeping the mass at 0.45 resulted in greater decoupling distance (74-88m, 14m altitude gain)
In conclusion:
When tested alone, there may sometimes be differences in decoupling distance, but since the Avionics Ring is typically used with a whole bunch of other stock parts to become a user-built Service Module (and becomes heavier in the process), the difference tends to be negated.
Additional feedback / info from Bomoo
As reported by forum user Bomoo and confirmed by my own testing:
The decoupler in the Avionics Ring appears to separate from the stock Mk1-2 Command Pod with greater force than the Service Module, even though both have
ejectionForce = 200
.Suspect minute differences in colliders.
