On a more realistic note, I have been tracking some compound stuff, and it seems to be:
Compounding level 1 jewels: 50%
Compounding level 2 jewels: 50%*
Compounding level 3 jewels: 25% (guessed)
Compounding level 5 jewels: 100% (public knowledge)
* might need further investigation

Note: I would really need to dig up some stuff I tracked during the first events, I know it is around somewhere. But this data is still better than nothing.
Calculating e.g. diamond boxes used while tracking:
2 * 30 + 25 = 85
