I suppose in answer to all of your points having been digging and acting as a council archaeologist since 1995 I cannot think of a single unexpected find that was found on a genuinely blank field, I can think of lots where things were better or worse than the her predicted but not much that was 'there was nothing within 500m and now there is something of regional significance' and the figures from Scotland back this up! But I can't convince anyone, so I'll keep quiet!
