Omg I was mentioned :D Anyway, after reading your thing I just wanted to mention: after laying a trap, the 'attraction zone' doesn't kick in until 5 or so seconds after the trap was laid, so even if they spawn in the attraction zone they may escape due to the attraction zone not being activated yet. Also, chinchompa prices is stable at about 600-700 from what I've seen (might be wrong) so you still make good profit, but not as good as me and you who sold ours 1k each :P
