By PPCT, do you mean the pressure points such as infra-orbital, mandibular angle, clavical notch, etc.? Basically, trying to gain control through non-injurious pain-compliance?
Most agencies really don't seem to have a system of unarmed SD tactics in use. Officers receive training at the academy which varies over the years and seldom more than a refresher or two after that. Tactics/training lean towards take-downs for cuffing and weapons retention techniques. Much of it goes out the window as the conflict progresses into a wrestling match.
I have been trained on the pressure points as a method of gaining compliance from non-violent resistors or as a method of coaxing a prisoner to move here or there or sit down when unwilling.
If the system is beginning to fail for your agency, I suggest contacting a trainer and getting everyone back up to speed. Give it another go before switching. Keep in mind that officers generally retain only a fraction of the techniques unless the train constantly and consistently.
