From the cutting edge of cosmology: the YouTube link below has Sabine Hossenfelder in discussion with Subir Sarkar, exposing some issues with old assumptions about inflation, distance, peculiar motions, etc.
Sabine Hossenfelder and Subir Sarkar (March 1, 2020)
With regard to the UB model of counter rotating space levels, one expectation is that astronomers should detect a "Hubble flow" out to about "300 million light years" (100 Mpc). This is what we'd expect after 500 million years of gentle expansion, beginning from the end of the last contraction: during the first 100 million or so years, the rate of expansion would be increasing from zero to current cruising speed -- the current (local) Hubble rate, "H_0".
Beyond 100 Mpc, the systematic increase of redshift will be due to increasingly relativistic transverse velocities, assuming the rate of rotation increases with distance; i.e, not only do the outer space levels alternate their direction of rotation, but the 2nd outer space level rotates faster than the 1st, and the 3rd rotates faster than the second. If this sideways motion ("transverse velocity") is any significant fraction of the local speed of light, then this model predicts those enormous red-shifts astronomers observe, which led theorists to believe in a simple Big Bang.
"By this method of reckoning, subsequent to the perfection of more powerful telescopes, it will appear that these far-distant systems are in flight from this part of the universe at the unbelievable rate of more than thirty thousand miles a second." (UB 12:4.14)
That confusing "local" rate of expansion is what I point to in the second half of that early draft, glimpsed last year in Chicago. See pages 50 and 51 (numbered 111, 112) int the second half of the script, link here: http://ubron.org/groupdocs/P4D_Issues_Nov01.pdf

Hope all are well!
