Free food & cooking tip: The only test that matters (step 2 of 8 from "Artisan Sourdough Bread").
Mark the jar with a rubber band after feeding. When the volume has roughly doubled and a spoonful looks airy, it is ready. The 'float test' is optional and lies when the starter is oily.
Do not add sugar or yeast 'to help it'. That is a different bread.
