Our club puts on some events now and then with several disciplines to shoot, and your version with a penalty for a faceplate is adopted into what we call Humane HFT. We deliberately portray it as a simulated hunting environment, just for that event.

It's quite a challenge for some regular HFT shooters to decide actually not to take the shot if they are not confident of a knock down.

In the end it's just another take on a target shooting sport.
