Why 3? What are you aiming/optimizing for?
Are you on primal or amethyst? You have way too many inbox/outbox relays. If you are on Primal go to https://metadata.nostr.com/ log in, click relays and pick 3 that you are SURE to have all of your posts and mark them as WRITE. Then pick 3 (it can be the same) that ANYONE can write into (no paid relays) and select READ.
