This moisture thing is tricky...When I bought my boat we metered a spot on the bottom at 90. The meter my surveyor used is a comparative meter so it works a bit differently than the standard type. The numbers don't exactly correspond to percents, however that number was too high for me. Due to some mitigating circumstances I was able to request and get permission to do a core test on my boat. The spot that metered at 90 ended up being basically dry. A small section of the hull had de-bonded which is not the same as de-laminated and we got a false reading. We did two other core tests and found some very old moisture that had been present in the boat from osmotic pressure. I had my local (not the yard guy at the marina where my boat was located) inspect the core we removed. He agreed that some elevated moisture was present, However he assured me that it would take 25 years before this could ever become a problem. He also offered me some "easy" solutions that I can do over the years I own the boat to prevent serious or permanent damage. Their is a difference between moisture that all boats with cored hulls have and saturation. Don't be afraid to ask for a core test and definitely don't be afraid to walk away from a boat. There are alot of J's out their and it is a buyers market. I almost walked away from the one I bought until I did the core test. If you want to check my boat out it is listed on Boats.com with a sale-pending marker. The boat is currently called divini smile but is soon to be Velocity girl. You can see how nice this boat is, but I was not afraid to dump it if the core results were not good.
