If you haven't stood on the top of the Inn Pinn, can you claim a full munro round?
If you haven't stood on top of the Cobbler after going through the needle, have you done all the corbetts?
Or if you've got to a snow covered summit and can't find the actual highest point or can't risk it due to cornicing issues (cause it situated on the edge) etc. do you need to go back and do without the snow cover? Doesn't apply to Everest or other permanently snow covered peaks.
