Warped poplar

Q: We specify 6 to 8 percent moisture content on the 5/4 poplar we buy. There have been a number of failures in dining tables as far as warping. The 5/4 that came in today had an average MC of 8.3 percent, with the highest at 9.1 percent and the lowest at 7.8 percent. We realize this is too high, but could you tell us the max and min we should be demanding?
