I never lift the fingers above the keys when playing. I'm loud enough, IMHO.
You can get away with things in your teens and twenties, that you will regret in your fifties and sixties. Ergonomics specialists in factories constantly have to repeat, "Don't use your hand as a hammer". Testosterone hides a lot of errors past the age of twelve, that come back to haunt one in the later years as arthritis. I am 63 and have a little arthritis in the hands, but not enough that I am not playing piano better than I ever have. In my knees, however, where the Army made me run in combat boots for 18 years. I'm much more limited by the pain. Knee X-rays confirm, there is hardly any cartledge left for cushioning. Hands are also full of cartledge that can be damaged by over-stress.
If you want a sharper ping at the beginning of the note, get a different piano. Yamaha & Wurlitzer studio models seem to be over mellow in tone with a soft attack. Steinways Sohmers and Hamilton by Baldwin consoles are in the middle. Baldwin Acrosonic consoles and old Bosendorfer grands have the sharpest ping. With all fifties-sixties consoles except the Steinway Yamaha and Bosendorfer going for $200 these days, with a little spare room you could have a collection.
