Degree of Certainty Cutoff Values for 95% Specificity

C2-A1	C2-A2	C3-A1	C3-A2	C3-A3	C3-A4	C3-A5	VFI	MD
0.821	0.852	0.825	0.810	0. 935	0.822	0.855	0.501	0.500

The columns C3-A1 to C2-A2 are axis projections of VIM, with C3-A1, for example, meaning axis 1 of cluster 3. The DOC cutoff proportions for VIM axes are higher than the 50% proportion for VFI and MD, since VIM progression is designated if any axis out of seven is progressed. GPA is not included, because its method does not permit adjustment of specificity.
