General help

Hi! I have this starter that is currently on day 7. It has gone through its false rise and is currently bubbling happily. I’ve been doing a lot of reading and a lot of people say to do a smaller starter to begin with. I am currently feeding mine 1 cup of flour and approximately 3/4 water twice a day. I’ve gotten that this is way too much and wasteful - so should I bring my starter down to 30 grams and feed smaller amounts? I am in no rush to get this going - more wondering if I am being wasteful.

Thank you!
