I didnt judge at the royal, but I can talk to a little of the score variances person to person. I was judging this weekend and we had 2 judges just absolutely love one entry, and 2 other of us absolutely hated the entry. Later I found out that of the judges the 2 that loved this entry were smokers, and the 2 of us that hated the entry were life-long non-smokers. Apparently our taste buds are very different. In this case, the BBQ to me had a VERY strong charcoal flavor, to the point where I couldnt get it out of my mouth... The other 2 guys who loved this entry couldn't taste that at all...
Same product, just 6 very different opinions, 2 strongly one score range, another 2 at the opposite end of that score range.
