Starting at "a concrete basis for performing repeatable, independent experiments" is a skyhook. Scientists have a hand in generating that "basis" and it's called inductive logic.
I think we agree on the fact that the production of knowledge involves the testing of hypotheses but not whether the generation of hypotheses via observation of phenomena is part of science. Semantic, I suppose, but I think it's crucial to take the rudder so to speak by developing hypotheses deliberately.
