i think i understand the basic idea behind the advice to remove as much starter as you put in- that with limited space in one's jar, you need to remove "waste" products to provide more room for the fresh food you add so the ratio is favorable to the type of bacteria you want to grow.
but if you have enough space in your jar to keep feeding in ample amounts, does it affect the quality of a starter to nor remove any some weeks? i tend to only use it once a week or less, and don't like wasting starter when i don't need it.

anyone have any experience to share?

thanks in advance.
