when u take and put symbel item in the table the hunger modifier get more % example i took and putted in linen table cloth and my hunger modifier got this 68->75.2%
well, if the hunger modifier gets higher, it means, it's worse. You'll get more stomach filled with the same bite. So, I suspect, that someone with much better sqrt(PSY*cooking) set the table, and when you took out the linen cloth, and put it back in, it caused the 'tidyness' to drop a lot, resulting in lesser hunger bonus.
