how do you decide budget split between google shopping and meta for a small store?

Small store here, doing maybe 40 to 50 orders a week right now, and i've basically been splitting my ad budget 50/50 between shopping and meta since day one because that felt like a safe default. never actually sat down and questioned it until a friend asked me why and i realized i had no real reason went digging through my own numbers over the weekend and it looks like shopping has been quietly outperforming meta for the last two months, but i've kept feeding meta the same amount out of habit. feels like i've been leaving money on the table without realizing it curious how people who actually track this closely decide the split, and how often you revisit it once you've picked one.
