Since the TOP500 project was started in 1993, supercomputers in the United States have always made up the majority of the world's super-compute performance (TOP500, 2019). According to TOP500's biannual report, the share of super-compute based in the United States peaked in November of 2008 at 67.02%, and has since been declining most years and was 28.18% in June 2020.
What share (in %) of the world's super-compute performance will be based in the United States in the November 2022 publication of TOP500 list?
The question resolves as the share of the world's super-compute performance at the maximum achieved performance on the LINPACK benchmark (Rmax), in teraFLOPS, that is based in the United States in the November 2022 TOP500 list.

[fine print] This question resolves ambiguously if TOP500 stops reporting performance in terms of Rmax measured in TFlop/s on the Linpack benchmark. [/fine-print]
