Jack, I think perhaps you aren't seeing the real issues here:
First: each entry has not one, but *three* scores, that might vary by as much as 5-7 points. The judges each take *their* top three, and discuss them with the other 2 judges at that table, and eventually come to a consensus of the top 3 for that flight.
A spreadsheet exercise would not be able to give you a sense of where you're at, because with 3 scores from the judges for your mead, you might be 10th, 13th and 17th in the same flight, which tells you nothing except that judge valuations vary all over the map.
Another thing: Assembling and managing the data in a competition this large is a *major* undertaking, and there are *never* enough people to do more than what we're doing now. As it is, data management goes on for days after the show just to deal with packing and shipping the scoresheets from the first and second round. I know, because I spend an afternoon at the MeadFest doing exactly that, with 2 other people.
Its not 'being unfair', its a sheer volume of data and the differences of opinion on each entry by three judges. That is why no competition in the country does this, they just issue the top 3 (or whatever level they medal), and send out the scoresheets for the rest.
It doesn't really matter where you are in the flight (unless you medal) anyway, because where you are in relation to the others is only valid for *that* festival for *that* year. Just because you were only 2 points behind 3rd place this year doesn't mean you won't be 15 points behind 3rd next year. Next year, you could enter the exact same thing, and do way worse or way better, depending on who else enters and what they enter.
Look at your scores, and where they fell against the 'perfect' score, i.e. a 50. Read the comments the judges left, and use that to learn to make a better competition mead. That is the purpose of the score sheet, not to rank you, but to give you a bench mark against the 'perfect' mead for that particular category.
Judging is a relative thing. And judging a mead (or wine or beer) isn't an exercise of 'is this mead a tastier or better mead than that mead', but more 'is this mead a better representative of its category than the other mead', which is a completely different thing. You aren't competing against the other meads, so much as you're competing against the 'perfect standard' for the category you enter.
