"... not improve it, via series inductances..."

dewster,
i meant the resulting SRF of stringing inductors will be always worse than a SRF of its particular member.

Generally speaking, the so-called "self capacitance  due interturn capacitance" is a myth multiplied in technical literature.
There is only a SRF as a primary phenomenon (caused by inductor wire to be a long transmission line).

Oops, I misread, sorry!

I know what you're saying, but self-capacitance is almost entirely determined by the physical winding method, hence single layer, pi-wound, multiple donuts, etc.
