Yes, I know. But my point was that sourdough, at least the one I keep, are living things and are not consistently the same. Mine depends on the time I kept it in the fridge, the temperature it’s kept outside (which depends on the weather), on how active the last generation was and many other factors I have more or less under control. And that manifests in taste difference, raising power etc.
