We typically think of locks as increasing hold and control until the desired affect is met such as straining, snapping, tapping out etc. But locks can hard to set up an maintain until the desired affect is met under real resistance. And why aikido like styles can get blow back for their techniques BJJ styles systems tend to be better set ups to ensure the lock. Karate like style will sometime get a full or half lock and transition to striking (also a useful strategy) Kali like systems is where ive seen this the most is the use of what i describe to my students as a "pop lock" where the strategy is a quick snap of control to the joint - if it works to control can be continued as a standard lock or if there is decent resistance or in the chaos it just didnt work great it can be quickly abandoned (hopefully and likely still did some damage to the joint) and continue with the fight. Some locks lend themselves better to being pop locks but many locks can be used with the pop lock mentality. Pop locks can also be advantageous for doing a lock at a wide or further range than a tight controlling lock. Your thoughts and use of pop locks?
