Hello! https://www.openstreetmap.org/node/10974842645/history has gp = 49°40’41.83334” 18°44’23.16653” that was added in this edit (if I checked things correctly)
What you intended to express by using this unusual key? Is this tag needed?
Or maybe can it be expressed in a more typical way that would be easier to understand?
Or maybe this key can and should be documented as useful tagging schema?
