I suspect variables related to the success of decoupling speakers include the floor (i.e., concrete or suspended wood), the weight of the speakers, the stiffness and resonant frequency of the speaker box, the force generated by the drivers (i.e., larger woofers create more back pressure than smaller midrange or mid-woofer drivers), whether the speaker design is acoustic suspension or bass reflex, if and how the speakers are mounted on stands, the weight distribution of the speakers (i.e., heavier in the front?), and other variables.
I suspect factors affecting the decoupling medium include stiffness, number of coils, and degree of compression (if using springs), pressure, volume, and elasticity (if using an air bladder), hardness and elastic properties (if using an elastomeric material), and the ability of the medium to decouple in the horizontal plane as well as the vertical plane.
Manufacturers of things like spring supports, air bladders, and elastic support materials often give weight ranges to help customers select the right product but it would be very difficult to precisely account for all variables. This may partially account for differences in the degree and types of improvement heard by listeners using decoupling devices. Since most report hearing positive changes, it is probably a case of close enough being good enough.
