Robert,
When did fog start getting reported as a ceiling? 001OVC is a ceiling
report. Fog would be reported as 1/8F or smoke / haze would be 1/8K wouldn't
it?

Also, the controller reported that he couldn't see you, so he probably
couldn't determine if the runway was clear for your landing. I don't see
where the confusion is here. He told you to land at your own risk.

I think you're also skewing the situation to fit your personal
preferences (hence the comment about 1/2 dot off) rather than strictly
discuss the technicalities of the situation. The controller had no visual
sighting of you (or probably the runway) so there was nothing else for him
or her to say other than "not in sight, land at your own risk" regardless of
training level. You were gonna do what you were gonna do anyway, so who is
he or she to tell you you can't? He couldn't clear you to land unless he
knew the runway was clear could he? Based on your original comments the
airport wasn't closed.
