The glyphs do not disagree with the idea that 186 = 182 + 4:

Eb2-4	Eb2-5	Eb2-6	Eb2-7
177	178	179	180
Eb2-8	Eb2-9
1	2
Eb2-10	Eb2-11	Eb2-12	Eb2-13
3	4	5	6

Neither do they give any definite confirmation. The picture is too complex for that. However, the 'elbow ornaments' in Eb2-10 and Eb2-13 are of the same kind, indicating they belong together.
