What is the current estimated self-citation rate?  I have found an older
article that put estimated self-citation rates at 30% or above.

Seglen PO.  Citation rates and journal impact factors are not suitable for
evaluation of research.  Acta Orthop Scand 1998; 69 (3): 224 - 229.

To support this, it references:
