Note I am not claiming G actually did this expo himself; also note the re-enactment used identical
shaped objects with low multiples of the mass difference .
Yes indeed, the Pisa experiment has been repeated, not at Pisa, and it is clear he did not do it. Galileo often wrote about gedanken experiments as if he did them, and real experiments as if he imagined them.

bc thinks he may want to correctly correct the Wiki. and joyously awaits a free 60 micro-gal resolution sensor from the USGS.
*** My modern phys instructor (UCSB -- 1957) said G.G. posed the question, what happens when one cuts the rigid thread between two unequal masses while falling?
The talk discusses the non-SI, but not the experiment. And I would add the Eötvös confirmation.
