Gordon
The Gordon Count(+1 for 2-5; 0 for 6,7,8,9,A; and -1 for 10s) is slightly worse than HO1, but if u use the multiparameter tables, it is slightly better than HO1+multiparameter tables, with a BC of .98 & a PE of .922, compared to HO1's .891. Imagine using a concealed computer with that system. LOL...
Does anybody know where to get that system?
