Coupling coordination degree classification [31].

Coupling coordination degree	Coupling coordination type	Coupling coordination degree	Coupling coordination type
0.0 ≤ D ≤ 0.1	Extremely incongruous	0.5 < D ≤ 0.6	Primary coupling coordination
0.1 < D ≤ 0.2	Serious incongruity	0.6 < D ≤ 0.7	Intermediate coupling coordination
0.2 < D ≤ 0.3	Mild incongruity	0.7 < D ≤ 0.8	Good coupling coordination
0.3 < D ≤ 0.4	Primary incongruity	0.8 < D ≤ 0.9	High-quality coupling coordination
0.40 < D ≤ 0.50	Close to incongruity	0.9 < D ≤ 1.0	Extreme coupling coordination
