It is not so much that they are being suggested on what to score... it is that you are trying to set the same scale. 5 mm vs. 5 ft. which scale is your 5 on.... The TCs and reps should be looking across the scores and address any variance that is large to ensure that the judge is in the same scale as the rest of the judges. If the food sucks, it sucks. score it that way.... but the grey area is where the seasoned folks are trying to help.
The flaw is... that the scale does not have a defined starting point. Start at "6", which is average.... well average is different to different folks. and is average edible.... or does the average guy over smoke his meat.... so you are looking for the average champion's food.... etc...
Since there is not a defined scale, and there is a wide range of judging experience.... Those folks are just trying to help normalize the scale, not keep people from judging how they feel.
Well then based on what your saying Andy, I would venture a guess that the BOD needs to re-evaluate the judging procedure. Something isn't working here.
