Dels posts seem to point in the same direction... (ie no >laquer on very soft hammers except the top 6 or 7 notes on his new designed >panels) I've tried pretty hard to say exactly that.

When you arrive at a design approach that sounds good with the softest hammers you can get, you can be pretty sure that other boards you install conforming to similar design criteria will react similarly and also need a soft hammer. They won't all sound identical, by any means, but they will all need hammers of similar hardness to sound good. When you build the board yourself, you know how it was put together, what methods were used, how it matches the string scale, and the reasoning behind the details. Even then you can't say exactly how slight deviations from any given parameter will affect the final performance. You might have a good general idea, but not an exact prediction. Looking at a finished soundboard assembly, there are a lot of potentially critical pieces of information missing from the picture. You might be able to identify potentially serious problems in scale breaks and impedance concerns, but you can't tell much about the crowning and panel compression, nor about the load distribution and balance between scale and soundboard. The dynamics depend on everything working together. When a combination of dimensional realities differs significantly from a design approach you know and feel you have some control over, there are too many un quantified interactions of unknown variables involved to have more than a general idea of what to expect. Taking enough measurements and spending enough time, you can get a rough idea, but you can hear everything you are going to have any control over with a hammer change just by playing a few notes and listening to what you get back. >BUT... grin.. looks like I was barking up that old Satswookie tree I got >out back >again...
