If one was to try to program in a target dip, it would be no challenge as log as one wasn't also specifying a target blow at the same time. These are what would require a Strike Balance Ratio change you know how to do that. The problem is of course that there is no direct correlation between action leverage as measure by distance and by weight. But you could still use the Stanwood procedure of capstan relocation, or Gravigne's/Davenport's/whoever's method of knuckle relocation to satisfy these requirements. Bear in mind that while you may find your new cap/knuckle location on a couple of samples, while the rest of the keyboard when set up according to these samples may show considerable variation. (Remember the FW/BW fork in the road with the Stanwood method?) Which would mean that once the action is re-regulate with the new set-up, your aftertouch could stagger around significantly within the specific 10mm dip. The real answer to this is what is the difference between the string heights and the action cavity height (room under the pinblock). That'll set the linit of how short a blow you can have with this 10mm dip, as the SBR goes downwards. You can start off with a rigid 10mm dip, and depending on how high you can reset the hammer line (higher with lower SBRs and visa-versa) you can get aftertouch to happen at a reasonable point in this dip, with a range of SBRs. Specifying a 10mm dip is one thing, whether that is accompanied by a required blow (or further yet, on top of that, a specified aftertouch) is another. Maybe you should rephrase the question.
