Talk:Protractor rule

For rules like your second example, where a quantitative characteristic is specified, I'd be inclined to disallow such rules entirely, although they're technically legal. For qualitative rules (like your first example), applying the 'reasonable person' rule' would seem to be an appropriate thing to do; if they're one degree off, most people probably won't notice it; thirty degrees off would be quite definitely noticed. --FreeTrav 07:49, 19 Sep 2006 (GMT)
