Wrong Dimension in "45 Record Adapters Competition"

"45 adapters must be 1.5 inches around with a .25 inch hole in the center to work so all valid entries must conform to that size."

Subject to the condition quoted above, none of the adapters will fit onto the center pivot of the turntable. The center hole diameter specified by the RIAA is 0.286" +0.001" -0.002" (see https://www.aardvarkmastering.com/riaa.htm ). The competition notice should be corrected.

I'm finding my Phillips 212 turntable's spindle is actually bigger than specified (currently trying 7.35mm). So I'll be having a bit of a larger hole on mine.
