Defender front door pitch

Wondering if any one knows the pitch for a defender door. Bought my first defender just before lockdown as a 2 year project and have almost finished it... Good weather means I havnt minded laying out on the driveway working at it. I have a question though, I have been repairing my passenger front door. It has rotted just above the top hinge point causing the whole top half to push out when I close the door, I'm not sure what angle/pitch the top half should be? I have tried to measure my other door and the bulkhead. Getting about 5 degrees but wondering if someone actually knows before I make a patch and do it wrong.
