Short answer
Shelf availability is whether a SKU can actually be bought in a given dark store right now. Live on the app is not the same as on the shelf.
Formula
Availability = in-stock dark stores / dark stores where the SKU is listed
Worked example
Listed in 800 stores and in stock in 560 is 70% availability. The other 240 stores are silent lost sales.
