Just to elaborate, if you took the 4.232 (60%) overall of the "winning" entry and weighed what it deserves (1/5) (40%) against it, it would come out to a weighted average of 2.9392. If you gave LoadedTeaspoon's entry what it deserves, (about 3/5) it would come out with a weighted average of 3.6630000000000003.
If you gave Dave C's entry what it deserves (5/5) it would come out with a weighted average of 4.1942.
Please do right by the community and utilize the 60%/40% split that were a part of the rules.
