Thank you Terry, Actually that is what I do but I would have liked to check against "official" data. I'll try to contact Bluthner.

But even if such a beast did exist, my recommendation would be the same. As it has been written on this list many times in the past, "let the piano dictate the regulation specifications". If, by chance you are not aware of the process, I'll try at least to give you a start. Start with the keys. Use the fallboard and keyslip as guides for key height. Place action in piano and check blow range - can you adjust somewhere in a 1-3/4" to 1-7/8" range? What kind of dip do you have with a given blow - is it what you like? Adjust accordingly. Your strings will dictate let-off and drop. I guess I really don't understand why anyone would rely on published data for regulating an action. Isn't that a bit like only using the Yamaha PT-100 fixed tuner to tune your C-3? I have Randy's Action Handbook and find it a useful tool to use as a starting point for regulation - but even then, I always evaluate how well the handbook specs work with the action and adjust accordingly.
