The keys do feel like the DGX525 and DGX225 model keyboards. I'm not a piano player, but graded has to do with how hard you need to play the keys on the lower end of the keyboard to make the sound of the piano be loud compared to having to play the keys on the upper range, which requires less strength to have these keys play loud. This has to do with the length and number of strings on a real grand piano. On a real piano, the hammer strikes the strings and therefore this natural grading effect occurs and on a digital piano, this effect is manufactured into the action of the keys.
