The Cryo Cannon's ‘Fragile’ upgrade is described as "frozen targets can spontaneously shatter".
The way in which it is worded suggests that there is a random chance for frozen targets to shatter. What is this chance and does this chance depend on the type of enemy being frozen?

According to this video, the Fragile upgrade has a 50% chance on freeze to shatter regular enemies that are under 85% health, with an unknown chance to shatter Special Enemies that are below 100 Health
Edit: On personal testing, it seems like the chance is only calculated one time as soon as the enemy is frozen. Grunts usually lose ~15% of their health as you freeze them, so I've found this upgrade to be beneficial mostly when attacking large numbers of swarmers or grunts.
