WIN-COLUMN conversion #4 (last item) — GR/SM precision particle phenomenology (electroweak precision).
The SM's win: it computes Z-pole / W-mass / mixing observables to ~0.01-0.1% given ~19 fitted inputs.

DFD's position (honest):
  * Precision MACHINERY (EW radiative corrections, loop calcs) = SM/QFT. DFD's gauge sector IS the SM,
    so it inherits the identical machinery -> reproduces the same precision predictions => TIE.
  * DFD's EDGE the SM lacks: it DERIVES the SM's *input* parameters from M7=CP2xS3 topology -- the SM
    just FITS them. Fewer free parameters.
  * Honesty-guard: DFD's derived inputs are good to ~0.1-1%, NOT the 0.01% of the EW global fit. So DFD
    removes free parameters at modest precision; it does not improve the precision. => TIE, not a WIN.
