Ever heard anyone say "I cut this piece four times and it's still too short."?
wood is unstable WRT humidity,
We have a customer who does woodworking for large projects, such as world class concert halls. He must deal with trimming out the venue while the concrete is still giving up its water. The atmosphere will not reach its ultimate climate controlled humidity for weeks at least. Wooden flooring contractors will deliver the wood a few days in advance in order to allow the planks to adjust to local conditions which might be quite different from the warehouse.
