That sounds reasonable on paper. But in the real world it seems more 
complicated than that. Local noise can really throw things out of whack. When I 
operate from my city qth, I’m hamstrung with a constant S-5 noise level, and at 
times it gets up to S-8. There is no doubt it costs me 100’s of q’s in a 
contest.
