Pianoteq with Yamaha CLP_895GP

Dear all,
New owner of a Yamaha Clavinova CLP_895GP (Grand Touch action), I'm willing to use Pianoteq 9 to increase the overall playing experience. I've noticed that the clavinova outputs MIDI velocities in the range [20-105] mainly. It is very hard to go below 20, and above 105.
I tried to auto calibrate the curve but this is not yet totally satisfiying.
I'm wondering if some users have already tuned the velocity curve for this clavinova serie 800, mainly 885 and 895 which are the high end of the serie.

Many thanks
