That's the confusion I was trying to clear up in this note. The system values are _constraints_. It sets an upper bound on the maximum uclamp_min/max value the system will apply. For example if a task::uclamp_min=1024 but the system::uclamp_min=512 512, then effectively the task will only be boosted to 512. Once this restriction is left by setting system::uclamp_min=1024 again, then the task will get the boost value it requested. I'm open to suggestions on how to better explain this..
