Fencer: Unless your ratings changed after this seeding was made, it is not correct. Also, it is customary to list the ranking with the person.

Top bracket as 1-8
next------- as 4-5
next------- as 3-6
next------- as 2-7

If done in this manner it will makes it possible to have the top seeds meet in the semi final and the number 1 and 2 meet in the final. It is easier to follow using the numbers this way too. If the ranking were done with the top four seeds and the rest assigned randomly, then I suppose it's fine and doesn't matter. It certainly is an improvement. How did you do it?
