Gape is the inside gap between point and shank as published in a size table. Only values from the manufacturer's own page are marked Verified; flyhooks.org caliper readings are community verified; retailer tables stay unverified until the maker confirms them. Blank cells mean no source publishes that number for this size; the row is listed so you can see the size exists. Every field has a ? that opens a correction form for that exact value. See the methodology.
