More elsewhere does not make up for too few

ʿAzīz Hadith: At Least Two Narrators in Every Generation

If one generation has two narrators and another has four, the increase alone does not break this condition of ʿazīz.

But if any generation has only one narrator, the condition is not fulfilled, even if other generations have many.

Adding all names in the sanad is therefore not enough: consider each generation separately.
