>Scientists avoid attaching a number to something until there's an explanation, a theory, that makes the number both compelling and testable (i.e. falsifiable). //

Hubble seemingly ignored the outliers and drew a straight line through his data to create his eponymous "constant". Making a mark to work from isn't really unscientific it's just loose hypothesising - http://www.pnas.org/content/15/3/168.full.pdf+html.

Surely the fact that this meta-analysis has falsified the former claim [hypothesis] shows that it was scientific [at least under a Popperian formulation].

That's a perfectly reasonable use of statistics in reducing observations. The same method was used extensively in the recent hunt for the Higgs Boson, until the uncertainties in the process fell below 5 sigma, at which point a discovery was announced.

If it's not either derived from empirical observation or a reasonable extrapolation from established theory, it's ipso facto unscientific.

No, it only shows that one unscientific claim (based on no theory and no evidence) can appear to unseat another. And it's not a "falsification", because the original claim is unfalsifiable on the ground that it's not based on a testable theory.

Group A says, "It takes 10,000 hours ..." without any basis. Group B says, "Utter nonsense." This happens in astrology all the time. Does that mean astrology is science? The difference between astrology and science is that scientists won't make a prediction without an empirical basis and a theory about why it's so.


Based on your formulation it seems all new "scientific" [null] hypotheses are "ipso facto unscientific"?

For example c being constant is an axiomatic part of relativity. Ergo to you it seems, as this is not empirical nor an extrapolation but a new hypothesis that when postulated contradicts established science, this suggestion - and presumably the ensuing formulation - was, um, unscientific?

Now I'm happy to go with that, call it a philosophical treatise and recognise the axiomatic nature of relativity but at this point I think your definition of science is too tight; theoretical physics to me is a part of science. Indeed I'd say wild hypothesising can be (and is called) science depending really on what you do with those hypotheses.
