Score weighting factors by organization

I have been told by those in the know that the FBA is distributed as follows;
Presentation = 15%
Tenderness = 43%
Taste = 42%
This is used on the premise that each of 6 judges has a total of 33.333333 points to give for a total of 200 points per item judged if all 10's were given

GBA:
Taste x 4
Tenderness x 3
Overall Impression x 3
Appearance x 2

Taste, Tenderness & Appearance scores range from 10 - 7. Overall Impression is a unique score for each sample from 10 - 9.1. IOW, only one sample the table can get a 10 in OI. Only one could get a 9.9. A judge must give at least one 10 in each of the for criteria. Multiple 10's (or multiple 9's, etc) may be given in Taste, Tenderness & Appearance.

6 judges per table. The judge with the lowest cumulative score is dropped. A perfect score is 600
