T&M do mention Podkletnov in their paper. They admit that their effect
is smaller than previously claimed by him, but the main distinction
(generally ignored by many pundits) is that Podkletnov used an
"unaccelerated" (constant velocity) superconducting disk, whereas the
effect produced by T&M occurs *only* during acceleration.

That's not the way I remember it. Podkletnov did both:
"A high-temperature $YBa_2Cu_3O_{7-x}$ bulk ceramic superconductor with
composite structure has revealed weak shielding properties against
gravitational force in the state of levitation at temperatures below 70
$K$. A toroidal disk was prepared using conventional ceramic technology
in combination with melt-texture growth. Two solenoids were placed
around the disk in order to initiate the current inside it and also to
provide rotation about its central axis. Samples placed over the
rotating disk demonstrated a weight loss of 0.3-0.5\%. When the
rotation speed was slowly reduced by changing the current in the
solenoids, the shielding effect became considerably higher and reached
1.9-2.1\% at maximum."
