"It would see to me that placing the layers in parallel you would be
decreasing the inductance, ie.

 Total I = 1 / (1/Ifirstlayer) + (1/Isecondlayer)...+(1/Inthlayer)

Are you saying that even though it reduces the inductance it is still
a gain over using the equivelent larger gauge wire?"

        NEGATIVE.  The adjacent windings are effectively in
parallel, sharting the same flux linkages.  No effect on inductance
except for a very small increase due to the greater mean diameter.
