I edited my post with a short version of how to get it. I found the article very informative so I figured I'd share it.I don't know why you would want heavier than 75 ever... I'm almost avoiding practicing on my piano now after finding out how heavy it is compared the grand I have lots of time to play on (and a 20 minute drive away). I knew my piano's touch was heavier but adding a number to it just made it worse, mostly just because it made me aware of how much work my fingers were doing, not because I suddenly think my piano is impossible to play.
Not to be confrontational Nyir but it's the opposite. The lighter the touch the easier to produce loud sounds.All my Yammies just have 1,2 or 3 as adjustments. I'll have to use the nickel idea to determine the touch-weight. All I know is I play with more agility at their lightest adjustments...
Also, I believe my Clavinova has a high touch-weight, but it feels like a toy piano as soon as I play loud. The resistance just evaporates as if there's none at all. It's too complex for the touch-weight alone to sum everything up.
Also, I could be wrong, but for a digital piano touchweight might be a more essential factor simply because digital pianos are a lot closer to simple buttons with on/off (pressed/not pressed) positions as compared to acoustics, where the action plays a lot more in the overall feel.
