Forget repeatability because the world doesn't always work that way, each perception is a data point and you have to work with that.

"Forget it" I think not. I choose to believe that EVERY SINGLE TIME I (or anyone for that matter) strike a lit match (in the presence of enough Oxygen) to gasoline that it will, understandably, burst into flame. That is how my world works. I can be forgiven for the oversimplification I hope, but I'd like to see (perceive, to use your terminology) the "data point" in which that fails to be true. I can certainly "perceive" of a condition where it fails, but that's my over-active imagination. Repeatable experiment, drawing the same conclusion is the basis of the scientific method, when testing any theory, no?
