Product with no inventory tracking returns numbers for totalInventory and quantityAvailable

I have a variable product and each variant is set to not track inventory. The Storefront API however is returning 756 on product.totalInventory. Where does this number come from if there’s no inventory tracked?

On the product variants, it’s the same issue, each variant has a seemingly different value for productVariant.quantityAvailable. I’m getting the following numbers: 95, 87, -21, -3, etc. Again, where is this value coming from?

The quantity input is using the quantityAvailable in order to set a max limit to add to cart. Unfortunately I’m not seeing a way to check if inventory is being tracked using the Storefront API.
