For the superior item crystals, can u disassemble lvl 110/120 equips for a crystal 100% of the time, or only some of the time? thx

Lv110->30% chance to get one superior item crystal
10% chance to get 2 superior item crystals
Lv120->60%chance or 50% to get one superior item crystal
30% chance to get 2 superior item crystals
10% chance to get 3 superior item crystals
But you might get advanced item crystals if you disassemble Lv120 equips. The probability might be 10% or so.
The numbers are coming from my hundreds of disassembling.
Disassemble Lv130 equips to get superior item crystals with 100% chance? No way. I think nobody is stupid to do that.
