NMSGUT-III: Grand Unification upended
  We show that matter yukawa couplings of the New Minimal Supersymmetric
(SO(10)) GUT(NMSGUT) are subject to very significant GUT scale threshold
corrections. Including these threshold effects relaxes the constraint $
y_b-y_\tau\simeq y_s-y_\mu$ operative in $\textbf{10} -\textbf{120} $plet
generated tree level MSSM matter fermion yukawas $y_f$. We find accurate fits
of the MSSM fermion mass-mixing data in terms of NMSGUT superpotential
couplings and 5 independent soft Susy breaking parameters $M_0, M_{1/2}, A_0,
M^2_{H,\bar{H}}$ at $M_X$. The fits generally have elevated unification scale
$M_X$ near $M_{Planck}$, viable values of $\alpha_3(M_Z)$, and are consistent
with current limits on B violation, $b\rightarrow s\gamma$, muon magnetic
moment anomaly and Standard Model $\rho$ parameter. The associated novel and
distinctive soft Susy spectra have light gauginos, a \emph{normal} s-hierarchy
and Bino LSP. The Bino LSP is accompanied by second and first generation right
chiral sfermions light enough to mediate a consistent WIMP dark matter
co-annihilation cosmology and to be discoverable at LHC, while third generation
sfermions are in the LHC undiscoverable range of 3-50 TeV. The fits found
require $|\mu|,|A_0|\sim 100$ TeV which imply both deep CCB/UFB minimae and
stability of the MSSM standard vacuum on cosmological time scales. Our results
indicate that a consistent realistic phenomenology may be specifiable in terms
of SO(10) (NMS)GUT parameters at $M_X$ alone and that a new viable sector of
the soft supersymmetry parameter space may exist if flavour violation
constraints can be satisfied in the 43 dimensional parameter space.
