Sorry, YA was meant to be Yamaha.
Yes it works with the glue. The other way to do the soundboard is to form it in a huge machine by high pressure.
The S&S method is supposed to minimize the risk for cracks.
I should have said 3 - 6 %

What is YA?

Usually the saw mills got the timber laying in the lakes simply because it makes it much more easy to cut the wood and to prevent it from being disformed.
When cut into planks they were sent to the pianomakers who stored them steadily in barn-like houses for years. Violin makers would store wood for the next generation.
Cut into pieces for soundboards at least S&S would dry it down to 3% and glue on the ribs. Back in "normal" humidity the soundboard would "crown". Much later YA showed up this as a great new invention though it had been done by European an US manufacturers for decades.
