> How many decades of astronomical progress did we lose to Urban VII?

Good question. I've never thought of astronomy as characterized by a constant stream of progress building mainly on the work of past astronomers; instead, I've seen it as more in line with the model of "technology advances, with ancillary benefits to all sorts of different fields including astronomy". For example, radio telescopes owe a lot to progress in physics, but not very much to progress in astronomy specifically.

If that's the case, "none" is a very plausible answer to your question.

The math and development behind a geocentric model is fascinating in a kink of fractal way. Everything needs and receives its own adjustment.
